$��$-Mappings of triangular algebras

2013
Let $A$ be an algebra and $ $ an automorphism of $A$. A linear map $d$ of $A$ is called a $ $-derivation of $A$ if $d(xy) = d(x)y + (x)d(y)$, for all $x, y \in A$. A linear map $D$ is said to be a generalized $ $-derivation of $A$ if there exists a $ $-derivation $d$ of $A$ such that $D(xy) = D(x)y + (x)d(y)$, for all $x, y \in A$.

On the Closure of Triangular Algebras

American Journal of Mathematics, 1990
The author constructs triangular algebras in the hyperfinite \(II_ 1\) factor and in \(B(H)\) whose norm closures are not triangular. These examples answer the question about triangular algebras in the negative.
