DESCRIPTION:Speakers: Léo Schelstraete (MPIM)\n\nAbstract Homotopy Theory
  Seminar\nMonoidal categories\, informally known as “diagrammatic algebr
 as”\, are ubiquitous in representation theory and low-dimensional topolo
 gy. Diagrammatic algebras are often described by generators and relations\
 , leading to the “word problem”: given two composite cells in the gene
 rators\, how to tell if they are related by a sequence of relations? For a
 lgebras\, the solution is known as Gröbner bases\, and more generally\, a
 s rewriting theory.\nIn this talk\, I will explain how to extend rewriting
  theory higher\, motivated by diagrammatic algebras. Emphasis will be put 
 on various ideas coming from higher category theory (polygraphs\, semistri
 ct categories\, double categories).\n\nhttps://math-events.uni-bonn.de/eve
