Cohomology of p-groups of nil potency class smaller than p

Antonio Díaz Ramos, Oihana Garaialde Ocaña, Jon González-Sánchez

Let $p$ be a prime number, let $d$ be an integer and let $G$ be a $d$ -generated finite $p$ -group of nilpotency class smaller than $p$ . Then the number of possible isomorphism types…

The cohomology of the sporadic group $J_{2}$ over $F_{3}$

Antonio Díaz Ramos, Oihana Garaialde Ocaña

We describe the cohomology ring $H^{*} (J_{2}; F_{3})$ both as subring of $H^{*} (3_{+}^{1 + 2}; F_{3})$ and with an abstract presentation. We also give its Poincaré series. We use…

Homological Algebra on Graded Posets

Antonio Diaz Ramos

We describe the projectives in the category of functors from a graded poset to abelian groups. Based on this description we define a related condition, pseudo-projectivity, and we…

Cohomological uniqueness of some $p$ -groups

Antonio Díaz, Albert Ruiz, Antonio Viruel

In this paper we consider classifying spaces of a family of $p$ -groups and we prove that mod $p$ cohomology enriched with Bockstein spectral sequences determines their homotopy typ…
