An extension of the Wedderburn-Artin Theorem
In this paper we give conditions under which a ring is isomorphic to a structural matrix ring over a division ring.
متن کاملExtension to an invertible matrix in convolution
Let M+ denote the Banach algebra of all complex Borel measures with support contained in [0, +∞), with the usual addition and scalar multiplication, and with convolution ∗, and the norm being the total variation of μ. We show that the maximal ideal space X(M+) of M+, equipped with the Gelfand topology, is contractible as a topological space. In particular, it follows that every left invertible ...
