Boundary and shape of Cohen-Macaulay cone
Hailong Dao, Kazuhiko Kurano
Let be a Cohen-Macaulay local domain. In this paper we study the cone of Cohen-Macaulay modules inside the Grothendieck group of finitely generated -modules modulo numerical…
Floer cohomologies of non-torus fibers of the Gelfand-Cetlin system
Yuichi Nohara, Kazushi Ueda
The Gelfand-Cetlin system has non-torus Lagrangian fibers on some of the boundary strata of the moment polytope. We compute Floer cohomologies of such non-torus Lagrangian fibers i…
On the limit of Frobenius in the Grothendieck group
Kazuhiko Kurano, Kosuke Ohta
Considering the Grothendieck group modulo numerical equivalence, we obtain the finitely generated lattice for a Noetherian local ring . Let be th…
How can one measure group cohesion? From individual organisms to their interaction
Z. Di, M. Gho, X. Lu +4
Measuring atomic and molecular interactions was one of the main objectives of physics during the past century. It was an essential step not only in itself but because most macrosco…
Sequentially Cohen-Macaulay Rees algebras
Naoki Taniguchi, Tran Thi Phuong, Nguyen Thi Dung +1
This paper studies the question of when the Rees algebras associated to arbitrary filtration of ideals are sequentially Cohen-Macaulay. Although this problem has been already inves…
Integral Euler characteristic of Out F_{11}
Shigeyuki Morita, Takuya Sakasai, Masaaki Suzuki
We show that the integral Euler characteristic of the outer automorphism group of the free group of rank 11 is -1202.
