A Generalization of the Ishida Complex with applications

Laura Felicia Matusevich, Erika Ordog, Byeongsu Yu

We construct a generalize Ishida complex to compute the local cohomology with monomial support of modules over quotients of polynomial rings by cellular binomial ideals. As a conse…

Graded local cohomology of modules over semigroup rings

Byeongsu Yu, Laura Felicia Matusevich

We give a combinatorial description of local cohomology modules of a graded module over a semigroup ring, with support at the graded maximal ideal. This combinatorial framework yie…

Shape-Preserving Dimensionality Reduction : An Algorithm and Measures of Topological Equivalence

Byeongsu Yu, Kisung You

We introduce a linear dimensionality reduction technique preserving topological features via persistent homology. The method is designed to find linear projection which preserv…

Standard pairs of monomial ideals over non-normal affine semigroups in SageMath

Byeongsu Yu

We present stdPairs.spyx, a SageMath library to compute standard pairs of a monomial ideal over a pointed (non-normal) affine semigroup ring. Moreover, stdPairs.spyx provides the a…

Standard pairs for monomial ideals in semigroup rings

Laura Felicia Matusevich, Byeongsu Yu

We extend the notion of standard pairs to the context of monomial ideals in semigroup rings. Standard pairs can be used as a data structure to encode such monomial ideals, providin…
