Graded triangular algebras [PDF]
The Electronic Journal of Linear Algebra, 2014 The structure of graded triangular algebras T of arbitrary dimension are studied in this paper. This is motivated in part for the important role that triangular algebras play in the study of oriented graphs, upper triangular matrix algebras or nest algebras.

Classification of limits of upper triangular matrix algebras. [PDF]
, 1993 Let Tn be the operator algebra of upper triangular n × n complex matrices. Three families of limit algebras of the form lim (Tnk) are classified up to isometric algebra isomorphism: (i) the limit algebras arising when the embeddings Tnk→Tnk+1, are ...

Lexicographic semigroupoids. [PDF]
, 1996 The natural lexicographic semigroupoids associated with Cantor product spaces indexed by countable linear orders are classified. Applications are given to the classification of triangular operator algebras which are direct limits of upper-triangular ...

Order preserving limits of finite-dimensional nest algebras. [PDF]
, 2002 We introduce order conserving embeddings as a more general form of order preserving embeddings between finite dimensional nest algebras. The structure of these embeddings is determined, in terms of order indecomposable decompositions, and they are shown ...

Invariants of triangular Lie algebras [PDF]
Journal of Physics A: Mathematical and Theoretical, 2007 Triangular Lie algebras are the Lie algebras which can be faithfully represented by triangular matrices of any finite size over the real/complex number field. In the paper invariants ('generalized Casimir operators') are found for three classes of Lie algebras, namely those which are either strictly or non-strictly triangular, and for so-called special

Product of derivations on triangular banach algebras [PDF]
Journal of Hyperstructures, 2017 In this paper, we give a necessary and sufficient condition for the product of two derivations on the triangular Banach algebra to be a derivation. We also study the case where the product of derivations is commutative.
