Polynomial ultradistributions: differentiation and Laplace transformation

O. Łopuszański (2010)

Banach Center Publications

We consider the multiplicative algebra P(𝒢₊') of continuous scalar polynomials on the space 𝒢₊' of Roumieu ultradistributions on [0,∞) as well as its strong dual P'(𝒢₊'). The algebra P(𝒢₊') is densely embedded into P'(𝒢₊') and the operation of multiplication possesses a unique extension to P'(𝒢₊'), that is, P'(𝒢₊') is also an algebra. The operation of differentiation on these algebras is investigated. The polynomially extended Laplace transformation and its connections with the differentiation...

Positive vector measures with given marginals

Surjit Singh Khurana (2006)

Czechoslovak Mathematical Journal

Suppose E is an ordered locally convex space, X 1 and X 2 Hausdorff completely regular spaces and Q a uniformly bounded, convex and closed subset of M t + ( X 1 × X 2 , E ) . For i = 1 , 2 , let μ i M t + ( X i , E ) . Then, under some topological and order conditions on E , necessary and sufficient conditions are established for the existence of an element in Q , having marginals μ 1 and μ 2 .

Preduals of spaces of vector-valued holomorphic functions

Christopher Boyd (2003)

Czechoslovak Mathematical Journal

For U a balanced open subset of a Fréchet space E and F a dual-Banach space we introduce the topology τ γ on the space ( U , F ) of holomorphic functions from U into F . This topology allows us to construct a predual for ( ( U , F ) , τ δ ) which in turn allows us to investigate the topological structure of spaces of vector-valued holomorphic functions. In particular, we are able to give necessary and sufficient conditions for the equivalence and compatibility of various topologies on spaces of vector-valued holomorphic functions....

Product of vector measures on topological spaces

Surjit Singh Khurana (2008)

Commentationes Mathematicae Universitatis Carolinae

For i = ( 1 , 2 ) , let X i be completely regular Hausdorff spaces, E i quasi-complete locally convex spaces, E = E 1 ˘ E 2 , the completion of the their injective tensor product, C b ( X i ) the spaces of all bounded, scalar-valued continuous functions on X i , and μ i E i -valued Baire measures on X i . Under certain...
