Sigma-maps on triangular algebras Sánchez-Ortega, Juana Repka, Joe Martín-González, Cándido Álgebra Triangular algebras were introduced by Chase in the early 1960s. He ended up with these structures in the course of his study of the asymmetric behavior of semi-hereditary rings. Since their introduction, triangular algebras have played an important role in the development of ring theory. In the middle/late 1990s, several authors undertook the study of derivations and related maps over some families of triangular algebras. Here, we will focus our attention on σ-biderivations and σ-commuting maps of triangular algebras (σ is an automorphism of the algebra). We will introduce and describe a new class of automorphisms of triangular algebras, and provide many classes of triangular algebras whose automorphisms can be determined 2018-01-30T10:00:41Z 2018-01-30T10:00:41Z 2018 2018-01-30 conference output https://hdl.handle.net/10630/15087 eng Conferencia: Sigma-maps on triangular algebras Málaga, España Junio 2018 open access
