Leafwise flat forms on Inoue-Bombieri surfaces
No full textWe prove that every Gauduchon metric on an Inoue-Bombieri surface admits a
strongly leafwise flat form in its -class. Using
this result, we deduce uniform convergence of the normalized Chern-Ricci flow
starting at any Gauduchon metric on all Inoue-Bombieri surfaces. We also show
that the convergence is smooth with bounded curvature for initial metrics in
the -class of the Tricerri/Vaisman metric.Comment: 24 pages. Final version to appear in J. Funct. Ana

A note on the moments of the first-passage-time of the Ornstein-Uhlenbeck process with a reflecting boundary
No full textFor the Ornstein-Uhlenbeck process with a reflecting boundary the moments of the first-passage time through a constant boundary are obtained in a closed form that appears to be particularly suitable for computation purposes. This is achieved via the determination of the Laplace transform of the first-passage time probability density function by a method previously devised by L. M. Ricciardi and S. Sato [J. Appl. Probab. 25, No. 1, 43–57 (1988; Zbl 651.60080)] for the unrestricted case

Physical properties of amorphous Al-Gd-transition metal alloys
No full textAmorphous alloys of the composition Al65Gd15Cu20 and Al1Gd1Fe1 have been prepared by rapid quenching from the melt. The alloys have been studied by X-ray diffraction, thermal analysis and SQUID magnetization methods. Thermal analysis results show crystallization temperatures of 647 and 945 K for Al-Gd-Cu and Al-Gd-Fe, respectively. For Al-Gd-Cu, magnetization measurements show Curie-like behaviour with a localized Gd magnetic moment of 8.0mu(B). Magnetic measurements of Al-Gd-Fe show conventional ferromagnetic behaviour. The Curie temperature is found to be 275 K and a saturation magnetization of 124 emu/g is measured at 4.2 K in an applied magnetic field of 1 T.PT: J; CR: DUNLAP RA, 1989, PHYS REV B, V39, P4808 DUNLAP RA, 1990, J PHYS CONDENS MATT, V2, P4315 DUNLAP RA, 1990, UNPUB HE Y, 1988, SCIENCE, V241, P1640 INOUE A, 1981, J MATER SCI, V16, P1989 INOUE A, 1988, JPN J APPL PHYS, V27, P1796 INOUE A, 1988, JPN J APPL PHYS, V27, L1579 INOUE A, 1988, JPN J APPL PHYS, V27, L479 OHANDLEY RC, 1991, HDB MAGNETIC MATERIA, V6, P453 SRINIVAS V, 1990, J APPL PHYS, V67, P5879 SUZUKI RO, 1985, J MATER SCI, V18, P1195 YEWONDWOSSEN M, 1990, THESIS DALHOUSIE U YEWONDWOSSEN M, 1992, J PHYS-CONDENS MAT, V4, P461; NR: 13; TC: 1; J9: J NON-CRYST SOLIDS; PN: Part 1; PG: 3; GA: LC964Source type: Electronic(1
The distribution of first-passage times and durations in FOREX and future markets
No full textPossible distributions are discussed for intertrade durations and first-passage processes in financial markets. The view-point of renewal theory is assumed. In order to represent market data with relatively long durations, two types of distributions are used, namely a distribution derived from the Mittag Leffler survival function and the Weibull distribution. For the Mittag-Leffler type distribution, the average waiting time (residual life time) is strongly dependent on the choice of a cut-off parameter tmax, whereas the results based on the Weibull distribution do not depend on such a cut-off. Therefore, a Weibull distribution is more convenient than a Mittag Leffler type if one wishes to evaluate relevant statistics such as average waiting time in financial markets with long durations. On the other hand, we find that the Gini index is rather independent of the cut-off parameter. Based on the above considerations, we propose a good candidate for describing the distribution of first-passage time in a market: The Weibull distribution with a power-law tail. This distribution compensates the gap between theoretical and empirical results more efficiently than a simple Weibull distribution. It should be stressed that a Weibull distribution with a power-law tail is more flexible than the Mittag Leffler distribution, which itself can be approximated by a Weibull distribution and a power-law. Indeed, the key point is that in the former case there is freedom of choice for the exponent of the power-law attached to the Weibull distribution, which can exceed 1 in order to reproduce decays faster than possible with a Mittag Leffler distribution. We also give a useful formula to determine an optimal crossover point minimizing the difference between the empirical average waiting time and the one predicted from renewal theory. Moreover, we discuss the limitation of our distributions by applying our distribution to the analysis of the BTP future and calculating the average waiting time. We find that our distribution is applicable as long as durations follow a Weibull law for short times and do not have too heavy a tail
