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…

A local method for posets

Antonio Díaz Ramos

We propose some conditions on a poset that produce a small chain complex for its homology. This allows to compare simplicial complexes and Quillen's complexes under the same prism.…
