On triangular subalgebras of groupoidC*-algebras

Israel Journal of Mathematics, 1990
Let \({\mathfrak B}\) be a \(C^*\)-algebra with Stratile-Voiculescu masa \({\mathfrak D}\) and \({\mathfrak A}\) be a maximal triangular subalgebra of \({\mathfrak B}\) with diagonal \({\mathfrak D}\). In the article [\textit{J. R. Peters}, \textit{Y. T. Poon} and \textit{B. H. Wagner}, J. Oper.

On a generalized Jordan form of an infinite upper triangular matrix

Linear and multilinear algebra, 2021
Any square matrix over an algebraically closed field has a Jordan normal form. In this paper, we prove that every infinite upper triangular matrix over an arbitrary field has a generalized infinite Jordan normal form.

Cohomology of the triangular algebra and applications

2003
Let \(K\) be a commutative ring, \(A\) and \(B\) be two associative and unitary \(K\)-algebras and \(M\) be an \((A\otimes B^o)\)-module. We suppose \(A\), \(B\) and \(M\) \(K\)-projective. The triangular algebra associated to this triple \(A\), \(B\) and \(M\) is the \(K\)-module \(T=\left(\begin{smallmatrix} A&M\\ 0&B\end{smallmatrix}\right)\) with ...

Ideals in Triangular Af Algebras

Proceedings of the London Mathematical Society, 1994
An ideal \(\mathcal J\) is said to be join-irreducible if whenever \({\mathcal J}= {\mathcal F}\lor {\mathcal G}\) for ideals \(\mathcal F\) and \(\mathcal G\), then either \({\mathcal F}= {\mathcal J}\) or \({\mathcal G}= {\mathcal J}\). We study the class of join- irreducible ideals in those strongly maximal triangular UHF algebras which arise as ...

A note on algebra automorphisms of triangular matrices over commutative rings

Linear Algebra and Its Applications, 1990
It is shown that if R is a commutative ring with unity, then every R -algebra, automorphism of the algebra of upper triangular n × n matrices over R is inner.
