The Cohen-Macaulayness of the bounded complex of an affine oriented matroid
Ryota Okazaki, Kohji Yanagawa
An affine oriented matroid is a combinatorial abstraction of an affine hyperplane arrangement. From it, Novik, Postnikov and Sturmfels constructed a squarefree monomial ideal in a…
On CW complexes supporting Eliahou-Kervaire type resolutions of Borel fixed ideals
Ryota Okazaki, Kohji Yanagawa
We prove that the Eliahou-Kervaire resolution of a Cohen-Macaulay stable monomial is supported by a regular CW complex whose underlying space is a closed ball. We also show that th…
On the radical of multigraded modules
Viviana Ene, Ryota Okazaki
We define a functor $\rr^\ast$ from the category of positively determined modules to the category of squarefree modules which plays the role of passing from a monomial ideal to its…
