Landau and H. Widom proved trace asymptotics for tr uncated Wiener-Hopf operators with piecewise continuous symbol\, as the tr uncation parameter grows. We present an asymptotic trace formula for the p eriodic Schrödinger operator in dimension one\, which may be seen as an ex tension of Landau and Widom's results. The subleading order of the asympto tics identifies the spectrum of the periodic Schrödinger operator. This is joint work with Alexander V. Sobolev.  \n DTSTART:20171023T180000Z DTEND:20171023T190000Z LOCATION:room 5340\, CA\, Pav.
