Integral representations of the g -Drazin inverse in C * -algebras

N. Castro González, Jaromír J. Koliha, Yi Min Wei (2004)

Mathematica Bohemica

The paper gives new integral representations of the g -Drazin inverse of an element a of a C * -algebra that require no restriction on the spectrum of a . The representations involve powers of a and of its adjoint.

Integrals and Banach spaces for finite order distributions

Erik Talvila (2012)

Czechoslovak Mathematical Journal

Let c denote the real-valued functions continuous on the extended real line and vanishing at - . Let r denote the functions that are left continuous, have a right limit at each point and vanish at - . Define 𝒜 c n to be the space of tempered distributions that are the n th distributional derivative of a unique function in c . Similarly with 𝒜 r n from r . A type of integral is defined on distributions in 𝒜 c n and 𝒜 r n . The multipliers are iterated integrals of functions of bounded variation. For each n , the spaces...
