Title: 
Contractive vs Completely contractive maps over function algebras

Abstract: An equivalent formulation of Ando's (generalization of Nagy's theorem) theorem providing a unitary dilation for a pair of commuting contractions is the statement: every contractive homomorphism of the bi-disc algebra is completely contractive. This is not true for any function algebra in three variables leaving the question of function algebras in two variables other than the bi-disc algebra open. The answer to this question for a large class will be discussed.
