Are locally finite MV-algebras a variety?

open access: yes, 2022
We answer Mundici's problem number 3 (Mundici (2011) [37]): Is the category of locally finite MV-algebras equivalent to an equational class? We prove: 1. The category of locally finite MV-algebras is not equivalent to any finitary variety. 2.

On vector spaces and algebras with maximal locally pseudoconvex topologies

open access: yes, 1995
Let X be a real or complex vector space. We show that the maximal p-convex topology makes X a complete Hausdorff topological vector space. If X has an uncountable dimension, then different p give different topologies. However, if the dimension of X is at

Locally convex quasi C*-normed algebras

open access: yes, 2010
If A_0 is a C∗-normed algebra and τ a locally convex topology on A_0 making its multiplication separately continuous, then A~_0[τ ] (completion of A_0[τ ]) is a locally convex quasi ∗-algebra over A_0, but it is not necessarily a locally convex quasi ∗-

On the multiplier algebra of certain locally m-convex algebras

open access: yes, 2013
If A is a topological algebra, a bounded mapping T : A → A is called a left (right) multiplier on E if T(xy) = T(x)y (resp. T(xy) = xT(y)) for all x; y ∈ A; it is called a two-sided multiplier on E if it is both a left and a right multiplier.

Complete nondegenerate locally standard CR manifolds

open access: yes, 2000
Let M be a complete nondegenerate locally standard C R manifold. We show that a necessary and sufficient condition for M to be compact is that the Lie algebra of its infinitesimal CR automorphisms is semisimple.

Generating continuous mappings with Lipschitz mappings [PDF]

open access: yes, 2007
If X is a metric space, then C-X and L-X denote the semigroups of continuous and Lipschitz mappings, respectively, from X to itself. The relative rank of C-X modulo L-X is the least cardinality of any set U\L-X where U generates C-X. For a large class of

σ-Subnormality in locally finite groups

open access: yes, 2023
Let σ={σj:j∈J} be a partition of the set P of all prime numbers. A subgroup X of a finite group G is σ-subnormal in G if there exists a chain of subgroups X=X0≤X1≤...≤Xn=G such that, for each 1≤i≤n−1, Xi−1⊴Xi or Xi/(Xi−1)Xjavax.xml.bind.JAXBElement ...

Locally convex *- algebras [PDF]

open access: yes, 1976
Generalizamos algunos de los resultados conocidos sobre las C*-algebras al caso de una *-algebra localmente convexa. En particular, analizamos la continuidad de los funcionales positivos, construimos el espacio de los ideales primitivos y estudiamos una ...

A non-locally convex topological algebra with all commutative subalgebras locally convex

open access: yes, 1996
We construct a complete multiplicatively pseudoconvex algebra with the property announced in the title. This solves Problem 25 of [6]
