Decomposition Spaces in Combinatorics

By Nicolas Behr

Motivated by joint work with Joachim Kock (UAB Barcelona & U Copenhagen), I plan to present an introduction to the powerful machinery of decomposition spaces (also known as 2-Segal spaces) from the viewpoint of its applications to combinatorics and its computational properties.
