Generalized Derivation

SUT Journal of Mathematics, 2004
In this paper, an extension of the orthogonality results for dominant operators, \(p\)-hyponormal and log-hyponormal operators is presented. Some generalized commutativity results are also obtained.

A generalization of leftmost derivations

Mathematical Systems Theory, 1977
A generalization of leftmost derivation called depth-first derivation is defined. The main result, that the depth-first derivations of an arbitrary phrase-structure grammar generate a context-free language, is proved using a new technique in which families of equivalent depth-first derivations of one grammar are represented by single productions in a ...

DERIVATIONS ON MORITA RINGS AND GENERALIZED DERIVATIONS

Journal of Algebra and Its Applications, 2011
In this note, derivations on Morita rings (generalized matrix rings) are introduced and generalized derivations on rings are proved to be Morita invariant without involvement of any homology theory.

Conciliating Generalized Derivatives

2013
As a new illustration of the versatility of abstract subdifferentials we examine their introduction in the field of analysis of second-order generalized derivatives. We also consider some calculus rules for some of the various notions of such derivatives and we give an account of the effect of the Moreau regularization process.

Generalized global monotonicity of generalized derivatives

International Transactions in Operational Research, 1994
The gradient and the several kinds of its generalizations provide a very efficient tool in characterizing important properties of functions. Convexity and generalized convexity, which are central properties in many branches of Operational Research, can also be characterized by special properties (monotonicity and generalized monotonicity) of the ...
