2006-01-01BuchThe properties of differential-algebraic equations representing optimal control problems This paper outlines a procedure for transforming a general optimal control problem to a system of Differential-Algebraic Equations (DAEs). The Kuhn-Tucker conditions consist of differential equations, complementarity ...

2005-11-10BuchThe semistatic limit for Maxwell's equations in an exterior domain This paper provides a $L^p$-theory for the Maxwell-system in the semistatic limit case in an exterior domain. The problem under consideration is of mixed type, since the possibly nonlinear electric conductivity vanishes ...

2005-11-03BuchThe Theta-Maruyama scheme for stochastic functional differential equations with distributed memory term We consider the problem of strong approximations of the solution of Itô stochastic functional differential equations involving a distributed delay term. The mean-square consistency of a class of schemes, the Theta-Maruyama ...

2005-11-03BuchTopological analysis of qualitative features in electrical circuit theory Several qualitative properties of equilibria in electrical circuits are analyzed in this paper. Specifically, non-singularity, hyperbolicity, and asymptotic stability are addressed in terms of the circuit topology, which ...

2005-11-17BuchTopological index calculation of DAEs in circuit simulation Electric circuits are present in a number of applications, e.g. in home computers, television, credit cards, electric power networks, etc. The development of integrated circuit requires numerical simulation. Modern modeling ...

2011-08-11BuchTowards effective simulation of effective elastoplastic evolution This paper summarises the general strategy for time evolving finite elastoplasticity and outlines encountered computational challenges in form of numerical benchmarks. Each time-step of some natural implicit time-discretisation ...

2005-11-02BuchTransformation of Lebesgue Measure and Integral by Lipschitz Mappings We first show that {\sc Lipschitz} mappings transform measurable sets into measurable sets. Then we prove the following theorem:\par {\it Let $E\subseteq \mathbb{R}^n$ be open, and let $\phi: E\to\mathbb{R}^n$ be continuous. ...

2011-09-27BuchTwist operators in N=4 beta-deformed theory In this paper we derive both the leading order finite size corrections for twist-2 and twist-3 operators and the next-to-leading order finite-size correction for twist-2 operators in beta-deformed SYM theory. The obtained ...
-
2005-11-02BuchTwo dimensional KP systems and their solvability In this paper we introduce new various generalizations of the classical Kadomtsev-Petviashvili hierarchy in the case of operators in several variables. These generalizations are the candidates for systems that should play ...

2011-09-20BuchVariétés bipolaires et résolution d’une équation polynomiale réelle In previous work we designed an efficient procedure that finds an algebraic sample point for each connected component of a smooth real complete intersection variety. This procedure exploits geometric properties of generic ...
