DESCRIPTION:Title: <a href="https://researchseminars.org/talk/OSGA/63/">On
  branch points and C^{1\,1} pseudospherical immersions</a>\nby Shankar Ven
 kataramani (University of Arizona) as part of Online Seminar "Geometric An
 alysis"\n\n\nAbstract\nThis is a report of joint work with Toby Shearman. 
 The key result is that one can define a (local) winding number of the Gaus
 s Map for $C^{1\,1}$ hyperbolic surfaces in $R^3$ and this degree is an ob
 struction for approximation by smooth immersions in $W^{2\,2}_{loc}$. I wi
 ll discuss the ideas behind the proof\, as well as the motivation for stud
 ying this question\, which comes from the mechanics of non-Euclidean plate
 s.\n
