Abstract
Polynomialsp 1,(z),p 2 (z), of degreen are defined by the relation\(p_1 (z) + p_2 (z)\prod\nolimits_{i = 1}^3 {(z - b_l )^{v_1 } } = O(z^{ - n - 1} ),z \to \infty \), where\(\sum\nolimits_{i = 1}^3 {v_i = 0} \). We obtain the asymptotic behavior of these polynomials asn→∞ and show that it agrees with a previous conjecture.
