## Zeros' Asymptotic Distribution of Polynomials Orthogonal with Respect to Varying Weights

**abstract:**

By using the WKB method, we found the asymptotic distribution of
the zeros of some sets of polynomials orthogonal with respect to
varying weights, including the so called relativistic orthogonal
polynomials.
