Lie algebras: infinite generalizations and deformations [PDF]

open access: yes, 1990
There are many applications of Lie algebras to theoretical physics. This thesis is a study of some new mathematical structures which also are applicable to current physical ideas.

MODEL THEORY AND DIFFERENTIAL ALGEBRA

open access: yes, 2008
I survey some of the model-theoretic work on differential algebra and related topics. 1 Introduction The origins of model theory and differential algebra, foundations of mathematics and real analysis, respectively, may be starkly different in character ...

Connections on trivial vector bundles over projective schemes

open access: yesComptes Rendus. Mathématique
Over a smooth and proper complex scheme, the differential Galois group of an integrable connection may be obtained as the closure of the transcendental monodromy representation.

Computer Algebra and Differential Equations

open access: yes, 1994
The Computer Algebra and Differential Equations meeting held in France in June 1992 (CADE-92) was the third of a series of biennial workshops devoted to recent developments in computer algebra systems. This book contains selected papers from that meeting.

DIFFERENTIAL OPERATORS ON AZUMAYA ALGEBRAS AND HEISENBERG ALGEBRAS

open access: yesCommunications in Algebra, 2001
We use the definition of differential operators on noncommutative rings given by V.Lunts and A.Rosenberg to find the differential operators on Azumaya algebras and the Heisenberg algebras.

Differential Rates of Return and Residual Information Sets (A Discrete Approach) [PDF]

open access: yes
It is our purpose here to show the deep relationship between differential rates and their underlying information sets. To accomplish our task, we will make for the following stages: In the first place, we deal with scaled changes along a period and ...

Factorization Free Decomposition Algorithms In Differential Algebra

open access: yes, 1999
. We present an effective version of Ritt's algorithm. We apply material of (Boulier et al. 1995) for which we give new concise proofs. We present original results in constructive algebra that makes the algorithm flexible and simple. 1. Introduction

On defining ideals and differential algebras of Nichols algebras

open access: yesJournal of Algebra, 2011
This paper is devoted to understanding the defining ideal of a Nichols algebra from the decomposition of specific elements in the group algebra of braid groups. A family of primitive elements are found and algorithms are proposed. To prove the main result, the differential algebra of a Nichols algebra is constructed.

Abelian Extensions of Modified λ-Differential Left-Symmetric Algebras and Crossed Modules

open access: yesAxioms
In this paper, we define a cohomology theory of a modified λ-differential left-symmetric algebra. Moreover, we introduce the notion of modified λ-differential left-symmetric 2-algebras, which is the categorization of a modified λ-differential left ...

Long term nonlinear propagation of uncertainties in perturbed geocentric dynamics using automatic domain splitting

open access: yes, 2014
Current approaches to uncertainty propagation in astrodynamics mainly refer tolinearized models or Monte Carlo simulations. Naive linear methods fail in nonlinear dynamics, whereas Monte Carlo simulations tend to be computationallyintensive. Differential
