Divisible subspaces and problems of automatic continuity
Raising bounded groups and splitting of radical extensions of commutative Banach algebras
Let A be a commutative unital Banach algebra and let A/ℛ be the quotient algebra of A modulo its radical ℛ. This paper is concerned with raising bounded groups in A/ℛ to bounded groups in the algebra A. The results will be applied to the problem of splitting radical extensions of certain Banach algebras.
