Research for the spaces with actions of algebraic groups or Weyl groups

1. J.Sekiguchi研究了so（p, q）中伴随幂零轨道的闭包序。这项研究是德约科维奇和勒米尔的共同研究，将发表在《东北数学》杂志第2期。sekiguchi研究了klein引入的二十面体方程的均匀化解。这项研究是与E.Bannai， M.Koike和a.m enemasa共同完成的。部分结果将发表在《纯数学高等研究》上。T.Fujiwara研究了P^3(C) 4中由投影正则曲线构造的2束的“nef”条件。增田研究了以下内容。设X是一个在C上定义有A^1_*-振动的代数曲面，设ψ是X的一个自同构，然后她证明了在几种情况下ψ是一个自同构。这项研究是与miyanishi先生共同完成的，将发表在《数学》杂志上。Annalen.5。T.Fukui与Y.N.Obukhov和G.F.Rubilar研究了线性电动力学中的波传播，其结果将发表在《物理评论D》上。

1. J.Sekiguchi studied the closure ordering of adjoint nilpotent orbits in so(p, q). This research is a joint work with D.Z.Djokovic and N.Lemire and is to appear in Tohoku Math.J.2. J.Sekiguchi studied solutions of the homogenization of the icosahedral equation introduced by F.Klein. This research is a joint work with E.Bannai, M.Koike and A.Munemasa. A partial result is to appear in Advanced Studies in Pure Math.3. T.Fujiwara studied the "nef" condition for 2-bundles constructed by the projectified canonical curves in P^3(C).4. K.Masuda studied the following. Let X be an algebraic surface with A^1_*-fibration defined over C and let ψ be an etale endomorphism of X.Then she showed that ψ becomes an automorphism in several cases. This research is a joint work with M.Miyanishi and is to appear in Math. Annalen.5. T.Fukui studied wave propagation in linear electrodynamics with Y.N.Obukhov and G.F.Rubilar and the result is to appear in Physical Reviews D.
