In this paper we extend the characterization of characters given in [1], [2] and [8] onto m-pseudoconvex algebras. As a consequence (and a generalization) we give a characterization of continuous homomorphisms from m-pseudoconvex algebras into commutative semisimple m-pseudoconvex algebras.

A characterization of commutative Fréchet algebras with all ideals closed

W. Żelazko (2000)

Studia Mathematica

Let A be a commutative unital Fréchet algebra, i.e. a completely metrizable topological algebra. Our main result states that all ideals in A are closed if and only if A is a noetherian algebra

A characterization of complex $L_{1}$ -preduals via a complex barycentric mapping

Petr Petráček, Jiří Spurný (2016)

Commentationes Mathematicae Universitatis Carolinae

We provide a complex version of a theorem due to Bednar and Lacey characterizing real $L_{1}$ -preduals. Hence we prove a characterization of complex $L_{1}$ -preduals via a complex barycentric mapping.

A characterization of essential sets of function algebras

Jan Čerych (2004)

Archivum Mathematicum

In the present note, we characterize the essential set $E$ of a function algebra $A$ defined on a compact Hausdorff space $X$ in terms of local properties of functions in $A$ at the points off $E$ .

A characterization of F-algebras with all one-sided ideals closed

W. Żelazko (2005)

Studia Mathematica

We prove that a real or complex F-algebra has all left and right ideals closed if and only if it is noetherian.

A characterization of holomorphic germs on compact perfect sets

Graciela Carboni, Angel Rafael Larotonda (2004)

Commentationes Mathematicae Universitatis Carolinae

Let $K \subseteq ℂ$ be a perfect compact set, $E$ a quasi-complete locally convex space over $ℂ$ and $f : K \to E$ a map. In this note we give a necessary and sufficient condition — in terms of differential quotients — for $f$ to have a holomorphic extension on a neighborhood of $K$ .
