SUMMARY:Rishika Rupam (Texas A&M University): The Toeplitz kernel approach 
 in inverse spectral theory of differential operators
DESCRIPTION:Rishika Rupam: When does the spectrum of an operator determine 
 the operator uniquely? -This question and its many versions have been stud
 ied extensively in the field of inverse spectral theory for differential o
 perators. Several notable mathematicians have worked in this area. Among o
 thers\, there are important contributions by Borg\, Levinson\, Hochstadt\,
  Liebermann\; and more recently by Simon\, Gesztezy\, del Rio and Horvath\
 , which have further fueled these studies by relating the completeness pro
 blems of families of functions to the inverse spectral problems of the Sch
 röodinger operator. In this talk\, we will discuss the role played by the
  Toeplitz kernel approach in answering some of these questions\, as descri
 bed by Makarov and Poltoratski. We will also describe some new results usi
 ng this approach. This is joint work with Mishko Mitkovski. \nSlides: http
