Lifting the solutions of a Toeplitz type equation; the semigroup case X = TsXT*s
(Universita del Salento, 1995)
A Toeplitz operator with respect to a contractive representation {Ts} of an abelian semigroup Σ in a Hilbert space H is an operator X ∈ B(H) such that X = TsXT ∗ s for all s ∈ Σ. We show that if {Ts} has a minimal ...

A Wide Class of Ultrabornological Spaces of Measurable Functions
(Elsevier, 1995)
Our main result states that a bornological locally convex space having a suitable Boolean algebra of projections is ultrabornological. This general theorem, whose proof is a variation of the sliding-hump techniques used ...
