Automatic complementarity of some classes of annulator ideals in Banach algebras
Let \(0\to R\overset{i}\rightarrow U\overset{p}\rightarrow {A} 0\) be an exact sequence of continuous homomorphisms of Banach algebras. Some sufficient conditions for the existence of a continuous right-inverse to \(p\) is found.
