SUMMARY:Time-reversal and reflection symmetry in (2+1)-dimensional topologi
	cal phases
DESCRIPTION:Featuring Meng Cheng\, Yale University\n\nPart of the Condensed
	 Matter Theory Seminar Series.\n\nAbstract: There has been immense progress
	 recently in the understanding of interacting topological phases of matter 
	in the presence of symmetry. I will discuss recent developments for the cas
	e of time-reversal / reflection symmetry-enriched topological (SET) phases.
	 I will derive a simple formula for the ground state degeneracy of such SET
	s on non-orientable manifold. I then use these results to develop an unders
	tanding of anomalies associated with time-reversal / reflection SETs. If ti
	me permits\, I will discuss explicit constructions of time-reversal/reflect
	ion SETs\, including anomalous ones.
