On the commutator length of compact Lie groups
Juan Omar Gómez, Victor Torres-Castillo, Bernardo Villarreal
In this short note we show that the path-connected component of the identity of the derived subgroup of a compact Lie group consists just of commutators. We also discuss an applica…
A family of infinite degree tt-rings
Juan Omar Gómez
We construct a family of infinite degree tt-rings, giving a negative answer to an open question by P. Balmer.
On the Picard group of the stable module category for infinite groups
Juan Omar Gómez
We introduce the stable module -category for groups of type as an enhancement of the stable category defined by N. Mazza and P. Symonds. For groups of type which ac…
On the cohomological triviality of the center of the Frattini subgroup
Jaime Calles, José Cantarero, Juan Omar Gómez +1
We improve the existing lower bounds on the order of counterexamples to a conjecture by P. Schmid, determine some properties of the possible counterexamples of minimum order for ea…
