A well-known result of Rivlin states that if (p(z)) is a polynomial of degree (n), such that (p(z) \neq 0) in (|z|<1), then (\max _{1:} \quad, \quad|p(z)| \geqslant((r+1) / 2)^{n} \max _{1: 1},|p(z)|). In this paper, we prove a generalization and refinements of this result. 1994 Academic Prem. Inc.

## Abstract In this paper we obtain chromatic polynomials __P(G__; Ξ») of 2βconnected graphs of order __n__ that are maximum for positive integerβvalued arguments Ξ» β§ 3. The extremal graphs are cycles __C__~__n__~ and these graphs are unique for every Ξ» β§ 3 and __n__ β 5. We also determine max{__P(
