Title: A Rasmussen invariant for links in RP3 

Abstract: Khovanov homology for links in RP3 was described by Gabrovsek.  We will discuss how to deform this construction to arrive at a Lee homology theory and Rasmussen invariant for such links, as well as describe some applications for freely 2-periodic knots in S^3.

Best,

Ross
