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

β¦ Synopsis
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. Ranges of values of a implied by these conditions are also given.
