Semiclassical orthogonal polynomials on the unit circle.
Abstract: Semiclassical orthogonal polynomials on the unit circle
are examined. Special care is given to generalized Jacobi polynomials.

20002002:
Abstract: several ways to build rational approximations to various
species of analytic functions are examined. Special emphasis is put
on strong asymptotic estimates of the form
$ f(z) R_n(z) \sim \sigma(z) \rho^n(z)$, when such estimates are
available,
and on approximation to exponentials of polynomials.
