 Title: An update on the problem of openness of multiplication in a Banach algebra

 Abstract  
We review the recent progress on the question of when is multiplication in a Banach algebra open. We shall present a proof of the fact that for certain measure algebras convolution is not open. The state of the art concerning multiplication in various functions spaces that is open but not uniformly will be reported. The talk will comprise some improvements of joint work with Sz. Draga as well as some observations due to F. Nazarov.
