, 2010 We propose a definition of a "C * -Eberlein" algebra, which is a weak form of a C * -bialgebra with a sort of "unitary generator".

A Remark on C -Dynamical Systems in Hilbert C -modules
, 2007 In this paper we consider C 0 -group of unitary operators on a Hilbert C -module E. In particular we show that if A ⊆ L(E) is a C -algebra including K(E) and there is x ∈ E with < x, x >= 1 and if α t is a C -dynamics on A with generator δ and θ x ...

, 2001 Let (U(t))t≥0 be a C0-semigroup of bounded linear operators on a Banach space X. In this paper, we establish that if, for some t0> 0, U(t0) is a Fredholm (resp., semi-Fredholm) operator, then (U(t))t≥0 is a Fredholm (resp., semi-Fredholm) semi-group ...

, 2018 Given an operator K∈B(H), in this paper the authors introduce K-fusion frames as a generalization of fusion frames, defined as a sequence {Wi} of closed subspaces of the Hilbert space H. For K=1, this becomes a fusion frame. They prove some properties of
