Clojure Conj 2012 - Whence Complexity?
Whence Complexity? by: Michael Nygard Quantum Mechanics and General Relativity don't agree on much, but both claim that every physical process is perfectly reversible. The Second Law of Themodynamics says, "Not likely!" The Second Law may win in the long run, but today, at (nearly) every

Ximena Fernández 7/20/22: Morse theory for group presentations and the persistent fundamental group
Discrete Morse theory is a combinatorial tool to simplify the structure of a given (regular) CW-complex up to homotopy equivalence, in terms of the critical cells of discrete Morse functions. In this talk, I will present a refinement of this theory that guarantees not only a homotopy equiv

Francesca Tombari (5/9/22): What's behind the homotopical decomposition of a simplicial complex
Decomposing a simplicial complex by taking a covering of its vertices does not necessarily preserves the homotopy type of the original one. Thus, there is no hope in general to retrieve the homotopy type of the Vietoris-Rips complex of a metric space, just by studying Vietoris-Rips complex

Jonathan Barmak: Star clusters in clique complexes and the Vietoris-Rips complex of planar sets
Abstract: The star cluster of a simplex in a simplicial complex K is the union of the stars of its vertices. When K is clique, star clusters are contractible. We will recall applications of this notion to the study of homotopy invariants of independence complexes of graphs. If X is a plan
