Ideals and Subalgebras of a Function Algebra

Canadian Journal of Mathematics, 1974
Let X be a compact Hausdorff space and C(X) the set of all continuous complex-valued functions on X. A function algebra A on X is a uniformly closed, point separating subalgebra of C(X) which contains the constants.

Abelian Subalgebras and Ideals of Maximal Dimension in Solvable Leibniz Algebras

Mediterranean Journal of Mathematics, 2023
The paper under review is a study of abelian subalgebras and ideals of maximal dimension in finite dimensional Leibniz algebras over a field, and generalizes the authors' previous results on Lie algebras [J. Pure Appl. Algebra 218, No. 3, 497--503 (2014; Zbl 1281.17006)]. Recall that a right Leibniz algebra \(L\) [\textit{J.-L.

On ideal and subalgebra coefficients in semigroup algebras

Results in Mathematics, 2001
Let \(k\) be a field, let \(S\) be a semigroup, and let \(k[S]\) be the semigroup ring of \(S\) over \(k\). Suppose \(U\) is either a one-sided ideal of \(k[S]\) or else a \(k\)-subalgebra of \(k[S]\). It is shown that there exists a smallest subfield \(k'\) of \(k\) such that \(U\) is generated by elements of \(k'[S]\).

TL-Subalgebras and TL-Ideals of Sub-BCI-Algebras

2009 Second International Workshop on Computer Science and Engineering, 2009
In this paper, the concepts of TL -sub-algebras and TL -ideals of sub-BCI-algebras are introduced, A necessary and sufficient condition for a L- subset of sub-BCI-algebra to be a L -sub-algebra (ideal) is stated, and images and inverse-images of L -sub-algebra under sub-BCI-algebra homomorphism are studied.

Radicals and prime ideals in limit subalgebras of AF algebras

The Quarterly Journal of Mathematics, 1997
A \(C^*\)-algebra is said to be approximately finite (AF) if it is the norm-closed union of a nested sequence of its finite-dimensional \(C^*\)-subalgebras. Here, the author studies the radical structure of a family of nonselfadjoint subalgebras of AF \(C^*\)-algebras, the triangular AF (TAF) algebras.

Hesitant fuzzy dot subalgebra and dot ideals of B-algebra

Journal of Intelligent & Fuzzy Systems, 2022
In this paper, the notions of hesitant fuzzy dot subalgebras, hesitant fuzzy normal dot subalgebras, and hesitant fuzzy dot ideals of B-algebras are presented, and some of their features are examined, in this study. The homomorphic image and inverse image of hesitant fuzzy dot subalgebras, as well as the hesitant fuzzy dot ideal, are investigated.
