In this paper we obtain the strong asymptotics for the sequence of orthogon
al polynomials with respect to the inner product
(f, g)s = integral f(z)<(g(z))over bar>rho(0)(z) \dz\ + integral f'(z)<(g'(
z))over bar>rho(1)(z) \dz\,
where rho(0) and rho(1) are weights which satisfy Szego's condition, suppor
ted on a smooth Jordan closed curve or are.
