Schubert classes in the equivariant cohomology of the Lagrangian Grassmannian
Takeshi Ikeda
Let denote the Lagrangian Grassmannian parametrizing maximal isotropic (Lagrangian) subspaces of a fixed symplectic vector space of dimension For each strict partition…
The existence of finitely generated modules of finite Gorenstein injective dimension
Ryo Takahashi
In this note, we study commutative Noetherian local rings having finitely generated modules of finite Gorenstein injective dimension. In particular, we consider whether such rings…
Electronic structure and spontaneous internal field around non-magnetic impurities in spin-triplet chiral p-wave superconductors
Mitsuaki Takigawa, Masanori Ichioka, Kazuhiko Kuroki +1
The electronic structure around an impurity in spin triplet p-wave superconductors is studied by the Bogoliubov-de Gennes theory on a tight-binding model, where we have chosen $\si…
Syzygy modules with semidualizing or G-projective summands
Ryo Takahashi
Let R be a commutative Noetherian local ring with residue class field k. In this paper, we mainly investigate direct summands of the syzygy modules of k. We prove that R is regular…
Introduction to GR@PPA event generators for pp/ppbar collisions
Soushi Tsuno
We have developed an extended framework, named GR@PPA, of the GRACE system for hadron collisions. The GRACE system is an automatic Feynman diagram calculation system and an event g…
Regularities of ground states of quantum field models
Asao Arai, Masao Hirokawa, Fumio Hiroshima
Regularities and higher order regularities of ground states of quantum field models are investigated through the fact that asymptotic annihilation operators vanish ground states. M…
