No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-graduação em LiteraturaEste trabalho tem como objetivo reunir e recuperar leituras críticas esparsas da obra de João Simões Lopes Neto publicadas na revista Província de São Pedro e no suplemento literário Caderno de Sábado, facilitando a pesquisa de outros estudiosos interessados em sua obra. O trabalho de transcrição foi realizado seguindo as normas padronizadas pela Filologia contemporânea, a fim de determinar os critérios adotados para a transcrição dos textos. Num primeiro momento, apresenta-se a apreciação da obra simoniana por parte dos críticos e, num segundo momento, são apresentados os vinte e oito textos selecionados para a transcrição
A connected component of the moduli space of surfaces with
No full textAbstractLet S be a minimal surface of general type with p_g(S)=0 and K_s2⩾3 for which the bicanonical map ϕ:S→PK_S2 is a morphism. Then degϕ⩽4 by Mendes Lopes (Arch. Math. 69 (1997) 435–440) and if it is equal to 4 then K_S2⩽6 by Mendes Lopes and Pardini (A note on surfaces of general type with p_g=0 and K2⩾7, Pisa preprint, December 1999 (Eprint: math AG/9910074)). We prove that if K_S2=6 and degϕ=4 then S is a Burniat surface (see Peters (Nagoya Math. J. 166 (1977) 109–119)). We show moreover that minimal surfaces with p_g=0,K2=6 and bicanonical map of degree 4 form a four-dimensional irreducible connected component of the moduli space of surfaces of general type

A footnote to a theorem of Kawamata
No full textKawamata has shown that the quasi-Albanese map of a quasi-projective variety
with log-irregularity equal to the dimension and log-Kodaira dimension 0 is
birational. In this note we show that under these hypotheses the quasi-Albanese
map is proper in codimension 1 as conjectured by Iitaka.Comment: Added an addendum by O. Fujino, M. Mendes Lopes, R. Pardini and S.

Radio Emission in Atmospheric Air Showers : Results of LOPES-10
No full textLOPES is set up at the location of the KASCADE-Grande extensive air shower experiment in Karlsruhe, Germany and aims to measure and investigate radio pulses from Extensive Air Showers. Data taken during half a year of operation of 10 LOPES antennas (LOPES-10), triggered by showers observed with KASCADE-Grande have been analyzed. We report about results of correlations found of the measured radio signals by LOPES-10 with shower parameters
