Asymptotics of the orthogonal polynomials for the Szego class with a polynomial weight

S. Denisov, S. Kupin

Let p(t) be a trigonometric polynomial, non-negative on the unit circle. We say that a measure σbelongs to a polynomial Szego class, if the logarithm of its density is summable ove…

The Szego class with a polynomial weight

S. Denisov, S. Kupin

Let p be a trigonometric polynomial, nonnegative on the unit circle . We say that a measure on belongs to the polynomial Szego class, if $dσ=sigma'_{ac…
