On derivations over rings of triangular matricesA. L. Barrenechea and C. C. PenaUNCentro-FCExactas-NuCoMPA-Dpto. de Matematicas, Tandil, Pcia. de Bs. As., Argentina, ccpenia@exa.unicen.edu.ar / analucia@exa.unicen.edu.arAbstract: The purpose of this article is to describe the structure of derivations over general rings of upper or lower triangular matrices. Some examples are developed, together with a simple formula that gives the dimension of the module of derivations on the center of the underlying ring. Keywords: Derivations. Inner derivations. Lie brackets. General semigroup ring of a group on a ring. Central simple $k$ - algebras Classification (MSC2000): 16W25 - 46L57 Full text of the article: (for faster download, first choose a mirror)
