✦ Synopsis


The Sendov conjecture may be stated: If all zeros of a complex polynomial p z < < X Ε½ . Ε½ . lie in z F 1, then there is always a zero of p z , that is, a critical point of p z , in < < Ε½ . z y a F 1, where a is any zero of p z . We prove several cases for which the Sendov conjecture is true as well as some stronger results. The case where a is the root with pth largest modulus is also investigated.

The Sendov conjecture may be stated as: If all zeros of a complex polynomial Ε½ . < < X Ε½ . < < p z lie in z F 1, then there is always a zero of p z in z y a F 1, where a is Ε½ . any zero of p z . We find several easy to apply conditions for which this conjecture is true for polynomials of degree n.

In this paper we prove that Sendov's conjecture is true for polynomials of degree Ε½ . n s 6 we even determine the so-called extremal polynomials in this case , as well as for polynomials with at most six different zeros. We then generalize this last Ε½ . Ε½ . result to polynomials of degree n with at

The Evasiveness Conjecture for graph properties has natural generalizations to simplicial complexes and to set systems. In this paper we show that the Evasiveness Conjecture for simplicial complexes holds in dimension 2 and 3. We also present an infinite class of counterexamples to the Generalized A
