[Allan M Sinclair] -- Some of the results on automatic continuity of intertwining operators and homomorphisms that were obtained between and are here collected together to provide a detailed discussion of the. The automatic continuity of all time-invariant and causal linear operators turns out to be just one achievement of a far-reaching new theory on automatic continuity which also applies to the problem of continuity for algebrahomomorphisms, derivations, intertwining operators, and local by: 5.

In this note, we present a general automatic continuity theory for linear mappings between certain topological vector spaces. The theory applies, in particular, to local operators between spaces of functions and distributions, to algebraic homomorphisms between certain topological algebras, and to linear mappings intertwining generalized scalar operators.

We extend the automatic continuity theory for linear operators θ:X→Y which intertwine two given bounded linear operatorsT∈L X andS∈L Y on Banach spacesX andY, respectively. This is done both by relaxing the intertwining conditionSθ=θT and by enlarging the classes of operatorsT, resp.S, well beyond the decomposable operators.

Among the operatorsS captured by these extensions are Cited by: 8. mial operators are contained in the books 5, It is well known that awx linear operator on a Banach space becomes automatically continuous or bounded, which is the same under some additional conditions.

Among many interesting questions arising from these two notions, quite a few efforts has been put on the automatic continuity of such maps. Automatic continuity of linear operators.

Suppose that F: X → Y is a linear operator between two topological vector spaces (TVSs). The following are equivalent: F is continuous at 0 in X.; F is continuous at some point x 0 ∈ X.; F is continuous everywhere in X; and if Y is locally convex then we may add to this list.

for every continuous seminorm q on Y, there exists a continuous seminorm p on X such that q ∘ F ≤ p. study linear operators. While we will mainly work in Hilbert spaces, we state the general definitions in Banach spaces.
