Note: Unlike other weeks, there will be no pre-seminar this week. The main talk starts at 3:30, not 4:10.
Simplicial complexes and cubical complexes contain a lot of interesting combinatorics. In this talk, we will examine special cases of each, namely flag simplicial complexes and CAT(0) cubical complexes, and we will connect them by introducing the crossing complex. The crossing complex unlocks many deep similarities between these two notions: in this talk, we will use it to relate their \$f\$-vectors, topology and several other combinatorial properties.
The UW combinatorics seminar is inviting you to a scheduled Zoom meeting.
