Geometric purity and the frame of smashing ideals

Juan Omar Gómez, Maurcio Medina-Barcenas, Greg Stevenson +2

We introduce the notion of geometric purity in rigidly-compactly generated tt-categories by considering exact triangles that are pure at each tt-stalk. We develop a systematic stud…

Counting conjugacy classes of elements of finite order in p-compact groups

José Cantarero, Bernardo Villarreal

We express the set of representations from a cyclic -group to a connected -compact group in terms of the associated reflection group and compute its cardinality for each exot…

On the second homotopy group of the classifying space for commutativity in Lie groups

Bernardo Villarreal

In this note we show that the second homotopy group of , the classifying space for commutativity for a compact Lie group , contains a direct summand isomorphic to $π_1(G…

On families of nilpotent subgroups and associated coset posets

Simon Gritschacher, Bernardo Villarreal

We study some properties of the coset poset associated with the family of subgroups of class of a nilpotent group of class . We prove that under certain assumption…

Higher generation by abelian subgroups in Lie groups

Omar Antolín-Camarena, Simon Gritschacher, Bernardo Villarreal

To a compact Lie group one can associate a space akin to the poset of cosets of abelian subgroups of a discrete group. The space was introduced by Adem, F. Co…

The Complex of Affinely Commutative Sets

Omar Antolín-Camarena, Bernardo Villarreal

We show that for some classes of groups , the homotopy fiber of the inclusion of the classifying space for commutativity into the class…

Commutative cocycles and stable bundles over surfaces

Daniel A. Ramras, Bernardo Villarreal

Commutative K-theory, a cohomology theory built from spaces of commuting matrices, has been explored in recent work of Adem, Gómez, Gritschacher, Lind, and Tillman. In this article…

Classifying spaces for commutativity of low-dimensional Lie groups

Omar Antolín-Camarena, Simon Gritschacher, Bernardo Villarreal

For each of the groups , we compute the integral and -cohomology rings of (the classifying space for commutativity of ), th…

Cosimplicial Groups and Spaces of Homomorphisms

Bernardo Villarreal

Let be a real linear algebraic group and a finitely generated cosimplicial group. We prove that the space of homomorphisms has a homotopy stable decomposition…
