Symmetric matrices defined by plane vector sequences
Mikiya Masuda
Motivated by a work of Fu-So-Song, we associate a symmetric matrix to a plane vector sequence and give a formula to find the signature of in terms of the sequence .…
Gamma vectors of partitioned permutohedra
Tatsuya Horiguchi, Mikiya Masuda, Takashi Sato +2
We determine that -vectors of partitioned permutohedra, thereby generalizing a result of Foata and Schützenberger. Our result is closely related to a result of Athanasiadis on t…
Toric Schubert varieties and directed Dynkin diagrams
Eunjeong Lee, Mikiya Masuda, Seonjeong Park
A flag variety is a homogenous variety where is a simple algebraic group over the complex numbers and is a Boel subgroup of . A Schubert variety is a subvari…
Modular law through GKM theory
Tatsuya Horiguchi, Mikiya Masuda, Takashi Sato
The solution of Shareshian-Wachs conjecture by Brosnan-Chow and Guay-Paquet tied the graded chromatic symmetric functions on indifference graphs (or unit interval graphs) and the c…
-cohomological rigidity for smooth toric Fano varieties of Picard number two
Yunhyung Cho, Eunjeong Lee, Mikiya Masuda +1
The -cohomological rigidity conjecture states that two smooth toric Fano varieties are isomorphic as varieties if there is a -preserving isomorphism between their integra…
Regular semisimple Hessenberg varieties with cohomology rings generated in degree two
Mikiya Masuda, Takashi Sato
A regular semisimple Hessenberg variety is a smooth subvariety of the flag variety determined by a square matrix with distinct eigenvalues and a Hessenberg…
