Computation of some leafwise cohomology ring Open
Let $G$ be the group $SL(2,\mathbb{R})$, $P\subset G$ be the parabolic subgroup of upper triangular matrices and $Γ\subset G$ be a cocompact lattice. A right action of $P$ on $Γ\backslash G$ defines an orbit foliation $\mathcal{F}_P$. We c…

近年，気候変動による台風や降雨の規模の増大により，水災害による被災リスクが増大すること，および，想定を上回る水災害の発生が示唆されていることから，高潮や河川洪水による大規模水害を想定する必要がある．また，都市における水害の被災過程を高精度に予測するためには，地下空間などの都市構造を考慮した浸水解析が必要となる．そこで，本研究では高潮や河川洪水による地上・地下空間同時氾濫災害を解析可能な数値モデルを構築し，大阪市を対象として高潮および大和川の洪水氾濫を想定した浸水解析を実施し…
