On spherical ideals of Borel subalgebras
Archiv Der Mathematik, 2005Let \(G\) be a connected reductive complex algebraic group, and \(B\) be a Borel subgroup of \(G\) with unipotent radical \(B_u\). Let \({\mathfrak g}\), \({\mathfrak b}\), and \({\mathfrak b}_u\) denote the Lie algebras of \(G\), \(B\), and \(B_u\) respectively.

On Leibniz Algebras whose Subalgebras are Either Ideals or Self-Idealizing Subalgebras
Ukrainian Mathematical Journal, 2021Leibniz algebras were presented by \textit{A. Blokh} [Sov. Math., Dokl. 6 (1965), 1450--1452 (1966); translation from Dokl. Akad. Nauk SSSR 165, 471--473 (1965; Zbl 0139.25702)], who called them the \(D\)-algebras. Two decades later, \textit{J.-L. Loday} introduced them in [Enseign. Math. (2) 39, No.

Maximal Ideals in Subalgebras of C(X)
Proceedings of the American Mathematical Society, 1987Let X be a completely regular space, and let A(X) be a subalgebra of C(X) containing \(C^*(X)\). We study the maximal ideals in A(X) by associating a filter Z(f) to each \(f\in A(X)\). This association extends to a one-to- one correspondence between M(A) (the set of maximal ideals of A(X)) and \(\beta\) X.

Ideals and Subalgebras of a Function Algebra
Canadian Journal of Mathematics, 1974Let 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.

Symmetries of the Poset of Abelian Ideals in a Borel Subalgebra
Journal of Lie Theory, 2014The study of abelian subalgebras of a finite dimensional semisimple Lie algebra has an ancient root. In 1945, \textit{A. I. Mal'tsev} [Izv. Akad. Nauk SSSR, Ser. Mat. 9, 291--300 (1945; Zbl 0063.03728)] found the maximal dimension of the abelian subalgebras of a finite dimensional simple Lie algebra. Also in 1965, \textit{B. Kostant} [Topology 3, Suppl.

The Maximal Ideal Space of Subalgebras of the Disk Algebra
Canadian Mathematical Bulletin, 1975Let X be a compact Hausdorff space and C(X) the complexvalued continuous functions on X. We say A is a function algebra on X if A is a point separating, uniformly closed subalgebra of C(X) containing the constant functions. Equipped with the sup-norm ‖f‖ = sup{|f(x)|: x ∊ X} for f ∊ A, A is a Banach algebra.
