Gabriel Spectrum of Persistence Categories

Manu Harsu, Eero Hyry

We determine the Gabriel spectrum of a category of sheaves of vector spaces in purely topological terms. For every topological space , we prove that the Gabriel spectrum of ${\m…

Ephemeral Modules and Scott Sheaves on a Continuous Poset

Manu Harsu, Eero Hyry

By utilizing domain theory, we generalize the notion of an ephemeral module to the so-called continuous posets. We investigate the quotient category of persistence modules by the S…

Flat covers and injective hulls of persistence modules

Eero Hyry, Ville Puuska

Motivated by recent progress in topological data analysis, we establish a Matlis duality between injective hulls and flat covers of persistence modules. This extends to a duality b…

Finite presentation of finitely determined modules

Eero Hyry, Markus Klemetti

In this article we study certain notions of `tameness' for the persistence modules studied in topological data analysis. In particular, we show that after adding infinitary points…

A formula for jumping numbers in a two-dimensional regular local ring

Eero Hyry, Tarmo Järvilehto

In this article we give an explicit formula for the jumping numbers of an ideal of finite colenght in a two-dimensional regular local ring with an algebraically closed residue fiel…

Canonical modules of complexes

Maryam Akhavin, Eero Hyry

We define the notion of the canonical module of a complex. We then consider Serre's conditions for a complex and study their relationship to the local cohomology of the canonical m…
