Isometries of half supersymmetric time-like solutions in five dimensions
No full textSpinorial geometry techniques have recently been used to classify all half supersymmetric solutions in gauged five-dimensional supergravity with vector multiplets. In this paper we consider solutions for which at least one of the Killing spinors generates a time-like Killing vector. We obtain coordinate transformations which considerably simplify the solutions, and in a number of cases, we obtain explicitly some additional Killing vectors which were hidden in the original analysis. © 2010 IOP Publishing Ltd.Behrndt K, 1998, PHYS LETT B, V442, P97, DOI 10.1016-S0370-2693(98)01208-8; Cacciatori SL, 2003, J HIGH ENERGY PHYS; Elvang H, 2005, PHYS REV D, V71, DOI 10.1103-PhysRevD.71.024033; Elvang H, 2004, PHYS REV LETT, V93, DOI 10.1103-PhysRevLett.93.211302; Figueroa-O'Farrill J, 2007, CLASSICAL QUANT GRAV, V24, P4429, DOI 10.1088-0264-9381-24-17-010; Gauntlett JP, 2003, CLASSICAL QUANT GRAV, V20, P4587, DOI 10.1088-0264-9381-20-21-005; Gauntlett JP, 2003, PHYS REV D, V68, DOI 10.1103-PhysRevD.68.105009; Gauntlett JP, 2005, PHYS REV D, V71, DOI 10.1103-PhysRevD.71.025013; Gauntlett JP, 2005, PHYS REV D, V71, DOI 10.1103-PhysRevD.71.045002; Gillard J, 2005, CLASSICAL QUANT GRAV, V22, P1033, DOI 10.1088-0264-9381-22-6-009; Gran U, 2007, J HIGH ENERGY PHYS; Gran U, 2005, CLASSICAL QUANT GRAV, V22, P2453, DOI 10.1088-0264-9381-22-12-010; Gran U, 2006, NUCL PHYS B, V753, P118, DOI 10.1016-j.nuclphysb.2006.07.007; Grover J, 2007, CLASSICAL QUANT GRAV, V24, P417, DOI 10.1088-0264-9381-24-2-009; Grover J, 2008, J HIGH ENERGY PHYS; Gutowski JB, 2004, J HIGH ENERGY PHYS; Gutowski JB, 2007, J HIGH ENERGY PHYS; Gutowski JB, 2004, J HIGH ENERGY PHYS; Gutowski JB, 2005, J HIGH ENERGY PHYS; Gutowski JB, 2004, J HIGH ENERGY PHYS; Harvey F., 1990, SPINORS CALIBRATIONS; Klemm D, 2000, PHYS REV D, V62, DOI 10.1103-PhysRevD.62.024003; Klemm D, 2001, J HIGH ENERGY PHYS; Klemm D, 2001, PHYS LETT B, V503, P147, DOI 10.1016-S0370-2693(01)00181-2; Kunduri HK, 2007, J HIGH ENERGY PHYS; Kunduri HK, 2006, J HIGH ENERGY PHYS; Kunduri HK, 2007, J HIGH ENERGY PHYS; Lawson H.

General supersymmetric solutions of five-dimensional supergravity
No full textThe classification of 1-4-supersymmetric solutions of five dimensional gauged supergravity coupled to arbitrary many abelian vector multiplets, which was initiated in [15], is completed. The structure of all solutions for which the Killing vector constructed from the Killing spinor is null is investigated in both the gauged and the ungauged theories and some new solutions are constructed. © SISSA 2005.Aharony O, 2000, PHYS REP, V323, P183, DOI 10.1016-S0370-1573(99)00083-6; Behrndt K, 1998, PHYS LETT B, V442, P97, DOI 10.1016-S0370-2693(98)01208-8; BENA I, HEPTH0408106; Cacciatori SL, 2003, J HIGH ENERGY PHYS; Cacciatori SL, 2004, J HIGH ENERGY PHYS; Chamseddine AH, 2000, PHYS LETT B, V477, P329, DOI 10.1016-S0370-2693(00)00178-7; Chamseddine AH, 1999, PHYS LETT B, V460, P63, DOI 10.1016-S0370-2693(99)00761-3; CHONG ZW, HEPTH0505112, P9; CHONG ZW, HEPTH0506029; de Boer J, 2000, J HIGH ENERGY PHYS; Elvang H, 2005, PHYS REV D, V71, DOI 10.1103-PhysRevD.71.024033; Elvang H, 2004, PHYS REV LETT, V93, DOI 10.1103-PhysRevLett.93.211302; Gauntlett JP, 2003, CLASSICAL QUANT GRAV, V20, P4587, DOI 10.1088-0264-9381-20-21-005; Gauntlett JP, 2003, PHYS REV D, V68, DOI 10.1103-PhysRevD.68.105009; Gauntlett JP, 2003, J HIGH ENERGY PHYS; Gauntlett JP, 2004, COMMUN MATH PHYS, V247, P421, DOI 10.1007-s00220-004-1066-y; Gauntlett JP, 2005, PHYS REV D, V71, DOI 10.1103-PhysRevD.71.025013; Gauntlett JP, 2005, PHYS REV D, V71, DOI 10.1103-PhysRevD.71.045002; Gauntlett JP, 2003, J HIGH ENERGY PHYS; Gillard J, 2005, CLASSICAL QUANT GRAV, V22, P1033, DOI 10.1088-0264-9381-22-6-009; Gran U, 2005, CLASSICAL QUANT GRAV, V22, P2701, DOI 10.1088-0264-9381-22-13-013; GUNAYDIN M, 1985, NUCL PHYS B, V253, P573, DOI 10.1016-0550-3213(85)90547-4; Gutowski JB, 2004, J HIGH ENERGY PHYS; Gutowski JB, 2004, J HIGH ENERGY PHYS; HAWKING SW, 1983, COMMUN MATH PHYS, V87, P577, DOI 10.1007-BF01208266; Klemm D, 2000, PHYS REV D, V62, DOI 10.1103-PhysRevD.62.024003; Klemm D, 2001, J HIGH ENERGY PHYS; MACCONAMHNA OAP, HEPTH0505230; Mac Conamhna OAP, 2004, PHYS REV D, V70, DOI 10.1103-PhysRevD.70.105024; Maldacena J M, 1998, ADV THEOR MATH PHYS, V2, P231, DOI DOI 10.1023-A:1026654312961; POPE CN, 1982, J PHYS A-MATH GEN, V15, P2455, DOI 10.1088-0305-4470-15-8-025; Reall HS, 2003, PHYS REV D, V68, DOI 10.1103-PhysRevD.68.024024; TOD KP, 1983, PHYS LETT B, V121, P241, DOI 10.1016-0370-2693(83)90797-9; Witten E., 1998, ADV THEOR MATH PHYS, V2, P253, DOI DOI 10.1016-S0370-1573(99)00083-6; Witten E., 1998, ADV THEORY MATH PHYS, V2, P50528343

Five Dimensional Non-Supersymmetric Black Holes and Strings
No full textWe study non-supersymmetric solutions of five dimensional N=2 supergravity theories coupled to an arbitrary number of abelian vector multiplets. The solutions constructed can be considered as deformations of known supersymmetric black hole and string solutions. General constraints coming from the analysis of the equations of motion are derived. These represent explicit conditions on the charges of the black holes and strings. The constraints are analyzed for theories where the scalar manifolds are symmetric spaces and explicit solutions are constructed in cases where the prepotential of the theory factorizes into a linear and a quadratic term
Cosmological Einstein-Maxwell instantons and Euclidean supersymmetry: Beyond self-duality
No full textWe construct new supersymmetric solutions to the Euclidean Einstein-Maxwell theory with a non-vanishing cosmological constant, and for which the Maxwell field strength is neither self-dual or anti-self-dual. We find that there are three classes of solutions, depending on the sign of the Maxwell field strength and cosmological constant terms in the Einstein equations which arise from the integrability conditions of the Killing spinor equation. The first class is a Euclidean version of a Lorentzian supersymmetric solution found in [1, 2]. The second class is constructed from a three dimensional base space which admits a hyper-CR Einstein-Weyl structure. The third class is the Euclidean Kastor-Traschen solution. © SISSA 2011.BELAVIN AA, 1975, PHYS LETT B, V59, P85, DOI 10.1016-0370-2693(75)90163-X; BRYANT R, 1999, P AN HARM AN VAR MAY; Cacciatori SL, 2008, J HIGH ENERGY PHYS; Cacciatori SL, 2004, J HIGH ENERGY PHYS; Detournay S, 2009, J HIGH ENERGY PHYS, DOI 10.1088-1126-6708-2009-10-030; Dunajski M, 2001, DIFFER GEOM APPL, V14, P39, DOI 10.1016-S0926-2245(00)00037-1; Dunajski M, 2011, CLASSICAL QUANT GRAV, V28, DOI 10.1088-0264-9381-28-2-025007; Dunajski M, 2007, CLASSICAL QUANT GRAV, V24, P1841, DOI 10.1088-0264-9381-24-7-010; Gauduchon P, 1998, J GEOM PHYS, V25, P291, DOI 10.1016-S0393-0440(97)00032-6; GIBBONS GW, 1982, PHYS LETT B, V109, P190, DOI 10.1016-0370-2693(82)90751-1; Gillard J, 2005, CLASSICAL QUANT GRAV, V22, P1033, DOI 10.1088-0264-9381-22-6-009; Gran U, 2005, CLASSICAL QUANT GRAV, V22, P2453, DOI 10.1088-0264-9381-22-12-010; Grover J, 2009, NUCL PHYS B, V809, P406, DOI 10.1016-j.nuclphysb.2008.08.024; GROVER J, 2008, J HIGH ENERGY PHYS, pN2848; Grover J, 2009, J HIGH ENERGY PHYS, DOI 10.1088-1126-6708-2009-07-069; Gutowski J, 2010, J HIGH ENERGY PHYS, DOI 10.1007-JHEP07(2010)011; Gutowski JB, 2010, CLASSICAL QUANT GRAV, V27, DOI 10.1088-0264-9381-27-23-235017; Gutowski JB, 2010, PHYS LETT B, V693, P498, DOI 10.1016-j.physletb.2010.09.003; Gutowski JB, 2007, J HIGH ENERGY PHYS; Harvey F., 1990, SPINORS CALIBRATIONS; HITCHIN N, 1982, TWISTOR GEOMETRY NON; JONES PE, 1985, CLASSICAL QUANT GRAV, V2, P565, DOI 10.1088-0264-9381-2-4-021; KASTOR D, 1993, PHYS REV D, V47, P5370, DOI 10.1103-PhysRevD.47.5370; Klemm D, 2009, CLASSICAL QUANT GRAV, V26, DOI 10.1088-0264-9381-26-14-145018; Lawson H.

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
