On the third cohomology group of commutative monoids
María Calvo-Cervera, Antonio M. Cegarra, Benjamín A. Heredia
We interpret Grillet's symmetric thrid cohomology classes of commutative monoids in terms of strictly symmetric monoidal abelian groupoids. We state and prove a classification resu…
Bicategorical homotopy pullbacks
A. M. Cegarra, B. A. Heredia, J. Remedios
The homotopy theory of higher categorical structures has become a relevant part of the machinery of algebraic topology and algebraic K-theory, and this paper contains contributions…
Double groupoids and homotopy 2-types
Antonio M. Cegarra, Benjamín A. Heredia, Josué Remedios
This work contributes to clarifying several relationships between certain higher categorical structures and the homotopy types of their classifying spaces. Double categories (Ehres…
