+<WRAP box 90%>
+**//Abstract//**:
+In this talk, I will discuss several approaches to studying the face numbers of simplicial complexes, with a particular focus on obtaining lower bounds. These approaches include classical rigidity theory, Stanley-Reisner rings, and higher‑dimensional stress spaces. I will also describe a number of both classical and recent results on face numbers that have been obtained using these tools.
