Characterizations of Lie centralizers of triangular algebras

Linear and multilinear algebra, 2022
Let be an unital algebra over the complex field . A linear map ϕ from into itself is called a Lie centralizer at a given point if for all with ST = G. The aim of this paper is to give a description of Lie centralizers at an arbitrary but fixed point on ...

Structured Triangular Limit Algebras

Proceedings of the London Mathematical Society, 1997
A class of triangular UHF algebras are investigated which have the special property that there exists a sequence of unital multiplicative contractive finite-rank conditional expectations of the algebra into itself, which converges strongly to the identity, whose ranges form an increasing chain with dense union.

Involutions of the second kind for upper triangular matrix algebras

Communications in Algebra, 2022
Let UTn be the algebra of all n × n upper triangular matrices over a field F of characteristic different from 2. In the present work, we will prove that for every automorphism of order 2 on the field F there exists, up to isomorphism, a unique involution

Coordinates for Triangular Operator Algebras

The Annals of Mathematics, 1988
Let A be a Cartan subalgebra of a von Neumann algebra M. This means A is a masa in M, the set of unitaries \(u\in M\) satisfying \(u^{-1}Au=A\) generates M, and there is a faithful normal expectation from M onto A. The simplest example has \(M=M_ n({\mathbb{C}})\) with A its subalgebra of diagonal matrices. In their papers [Trans. Amer. Math. Soc. 234,
