We identify a class of smooth Banach *-algebras that are
differential subalgebras of commutative C*-algebras whose openness of
multiplication is completely determined by the topological stable rank
of the target C*-algebra. Finally, we completely characterise in the
complex case (uniform) openness of multiplication in algebras of
continuous functions in terms of the covering dimension. The talk will
be based on recent joint work with Tomasz Kania.
