Absolutely continuous spectrum of multidimensional Schrodinger operator
S. A. Denisov
We prove that 3-dimensional Schrodinger operator with slowly decaying potential has an absolutely continuous spectrum that fills the positive half-line. The asymptotics of Green's…

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…
