DESCRIPTION:Title: <a href="https://researchseminars.org/talk/ags/15/">Dis
 crete analytic functions and Schur analysis</a>\nby Daniel Alpay (Chapman 
 University) as part of Analysis and Geometry Seminar\n\n\nAbstract\nWe int
 roduce the Schur class of functions\, discrete analytic on the integer lat
 tice in the complex plane. As a special case\, we derive the explicit form
  of discrete analytic Blaschke factors and solve the related basic interpo
 lation problem. We define and study rational discrete analytic functions a
 nd prove the existence of a coisometric realization for discrete analytic 
 Schur multipliers. The talk is based on collaborations with F. Colombo\, K
 . Diki\, I. Sabadini and D. Volok.\n
