Equivariant CW-complexes homotopy equivalent to spheres: a survey
Ian Hambleton, Ergun Yalcin
This is a survey about finite group actions on CW-complexes and related topics, primarily based on our joint work. The main applications are to finite -CW-complexes which are ho…
Worst-Case Examples for the Computation of Persistent Homology
Uzay Çetin, Ergun Yalcin
We construct worst-case examples for the standard reduction algorithm for computing persistent homology. Our constructions are similar to the worst-case examples introduced by Moro…
Free actions on products of real projective spaces
Ergun Yalcin
We prove that if acts freely and cellularly on a finite-dimensional CW-complex homotopy equivalent to $\mathbb{R}P ^{n_1} \times \cdots \times \mathbb{R} P…
Thomason cohomology and Quillen's Theorem A
Mehmet Kirtisoglu, Ergun Yalcin
Given a functor between two small categories, there is a homotopy equivalence where is…
LHS-spectral sequences for regular extensions of categories
Ergun Yalcin
In [F. Xu, On the cohomology rings of small categories, J. Pure Appl. Algebra 212 (2008), 2555-2569], Xu constructs a LHS-spectral sequence for target regular extensions of small c…
Steenrod closed parameter ideals in the mod- cohomology of and
Henrik Rüping, Marc Stephan, Ergun Yalcin
In this paper, we classify the parameter ideals in and in the Dickson algebra that are closed under Steenrod operations. Consequ…
