چکیده
|
Let ℙ be the space of polynomials with complex coefficients endowed with a nondiagonal sobolev norm || · ||w 1,p (vμ),where the matrix v and the measure constitute a p -admissible pair for 1 ≤ p ≤ ∞. in this paper we establish the zero location and asymptotic behavior of extremal polynomials associated to || · ||w 1,p (vμ),stating hypothesis on the matrix v rather than on the diagonal matrix appearing in its unitary factorization. © 2013 ana portilla et al.
