Abstract
We study three closely related concepts in the context of the Banach algebra C_0(X,A). We show that, to a certain extent, Segal extensions, norm irregularity and the existence of approximate identities in C_0(X,A) can be deduced from the corresponding features of A and vice versa. Extensive use is made of the multiplier norm and the tensor product representation of C_0(X,A).
