Order and commutativity in Banach algebras

Autor: Philip C. Curtis

Publikováno v: Proceedings of the American Mathematical Society. 9:643-646

S. Sherman has shown [4] that if the self adjoint elements of a C* algebra form a lattice under their natural ordering the algebra is necessarily commutative. In this note we extend this result to real Banach algebras with an identity and arbitrary B

Nonanalytic functional calculi and spectral maximal spaces

Autor: Philip C. Curtis, Michael M. Neumann

Publikováno v: Pacific J. Math. 137, no. 1 (1989), 65-85

We are concerned with the algebraic representation of the spectral maximal spaces for certain classes of decomposable operators on Banach spaces. The main emphasis will be on those operators which admit a functional calculus on a suitable algebra of
