CHARACTERIZATION OF SOME BIDERIVATIONS ON TRIANGULAR BANACH ALGEBRAS [PDF]
, 2021 Let $A$ and $B$ be unital Banach algebras, $X$ be an unital $A-B-$module and $T$ be the triangular Banach algebra associated to $A, B$ and $X$. The structure of some derivations on triangular Banach algebras was studied by some authors.

Ternary mappings of triangular algebras [PDF]
, 2021 We take acategorical approach to describe ternary derivations and ternary automorphisms of triangular algebras. New classes of automorphisms and derivations of triangular algebras are also introduced and studied.Junta de Andalucía and Fondos FEDER ...

ON MULTIPLICATIVE LIE n-HIGHER DERIVATIONS OF TRIANGULAR ALGEBRAS [PDF]
, 2021 Let $\mathrm{R}$ be a commutative ring with unity, $\mathrm{A},\mathrm{B}$ be $\mathrm{R}$-algebras and $\mathrm{M}$ be an $(\mathrm{A}, \mathrm{B})$-bimodule. Let $\mathfrak{T}=Tri(\mathrm{A},\mathrm{M},\mathrm{B})$ be a $(n-1)$-torsion free triangular

Derivations and the first cohomology group of trivial extension algebras
, 2017 In this paper we investigate in details derivations on trivial extension algebras. We obtain generalizations of both known results on derivations on triangular matrix algebras and a known result on first cohomology group of trivial extension algebras. As

Jordan Derivations and Antiderivations of Generalized Matrix Algebras [PDF]
, 2012 Let $\mathcal{G}=[A & M N & B]$ be a generalized matrix algebra defined by the Morita context $(A, B,_AM_B,_BN_A, \Phi_{MN}, \Psi_{NM})$. In this article we mainly study the question of whether there exist proper Jordan derivations for the generalized ...

Lie derivations on trivial extension algebras [PDF]
, 2016 In this paper we provide some conditions under which a Lie derivation on a trivial extension algebra is proper, that is, it can be expressed as a sum of a derivation and a center valued map vanishing at commutators.

Supercommuting maps on unital algebras with idempotents [PDF]
Let $ \mathcal{A} $ be a unital algebra with nontrivial idempotents. We considered $ \mathcal{A} $ as a superalgebra according to Ghahramani and Zadeh's method. We provided a description of supercommuting maps on $ \mathcal{A} $.

Triangular algebras with nonlinear higher Lie n-derivation by local actions [PDF]
This paper was devoted to the study of the so-called nonlinear higher Lie n-derivation of triangular algebras $ \mathcal{T} $, where $ n $ is a nonnegative integer greater than two.

Bumblebee program, aerodynamic data. Part 2: Flow fields at Mach number 2.0 [PDF]
Available flow field data which can be used in validating theoretical procedures for computing flow fields around supersonic missiles are presented. Tabulated test data are given which define the flow field around a conical-nosed cylindrical body in a ...
