Seminario de Categorías

Expositor: Brendan Fong, Topos Institute

Resumen: We often understand our world piece by piece, weaving local models and perspectives into a bigger picture. In any category, amalgamating parts into a single object can be captured through the notion of colimit. Cospans provide a convenient syntax for performing this weaving, building colimits piece by piece. Through the use of decorated and structured cospans, this approach can extend to categories where colimits may be complicated to compute, or may not even exist at all. In this talk, I'll provide a perspective on both the power and limits of cospans as a tool for composition, meditating on why, how, and when cospans can contribute.
