Pure Maths Colloquium: Model categories and homotopy theories
7 October 2013 16:00 in CM221
This talk will mostly be an overview of the subject of abstract (categorical) homotopy theory and in particular Quillen model categories. These latter provide a general framework, increasingly proving useful in diverse areas, for approaching 'homotopy-theoretic' questions, such as derived functors. As an important example we will look at the model category of simplicial sets and some related constructions that provide simplicial and categorical 'models' of topological homotopy types.
