Expositor: Bernardo Uribe Jongbloed, Universidad del Norte
Resumen: Multiplicative gerbes can be understood as monoid objects on the 2-category of gerbes. We take this point of view on the 2-category of topological gerbes in order to define appropriate representations of these multiplicative gerbes.
We take an explicit model for topological gerbes using Graeme Segal's cohomology of topological groups and we show that with this model we may replicate several constructions done over multiplicative gerbes over finite groups.
