# Topology Seminar

**Day: Every Friday**

Time: 11 - 1:50 pm

Location: TBD

Time: 11 - 1:50 pm

Location: TBD

This is a faculty research seminar focused on topology and its applications, with occasional student presentations. Graduate and undergraduate students interested in topology and its applications are welcome to attend. Primary topics are geometric topology (manifolds, cellular/simplicial/combinatorial complexes, knots, geometric group theory etc.), point-set topology, and algebraic topology. Other topics applying topology in an essential manner are also presented, drawn from such areas as functional analysis, large dataset analysis, dynamical systems, geometry, category theory, computation, physics (string and gauge theory), biology, chemistry, economics, finance, electrical engineering, and systems engineering. The week before each talk, the department website has a posting of the speaker, the talk title, and an abstract summarizing the presentation, as well as the date, time, and location of the talk.
