" The Szego Class "
Abstract: The nineteen-year-old student G.Szego proved in 1915 the conjecture of G.Polya about asymptotics of the Toeplitz determinant. This initiated analysis of spectral measures from the Szego class. Orthogonal polynomials with respect to such measures enjoy several nice asymptotics. We review some results in this direction and discuss a possible form of the Szego condition for singular continuous measures.
