Asymptotics for extremal polynomials with varying measures
Electronic transactions on numerical analysis, Tome 19 (2005), pp. 29-36
In this paper, we give strong asymptotics of extremal polynomials with respect to varying measures of the form d$\sigma n = d\sigma $, where $\sigma $is a positive measure on a closed analytic Jordan curve C, and Y |Y |p n is a n sequence of polynomials such that for each n, Yn has exactly degree n and all its zeros $(\alpha n,i)$, i = 1, 2, . . ., lie in the exterior of C.
