Title: A cohomological proof for the integrability of strict Lie 2-algebras

Speaker: Camilo Angulo

A strict Lie 2-algebra is a groupoid object in the category of Lie algebras. These can naturally be seen as an infinitesimal version of strict Lie 2-groups which are groupoids in the category of Lie groups. Lie 2-algebras were proven to be integrable in this sense using the path strategy to integration, we present an alternative proof based on the van Est strategy.
