Variational Problems with Concentration Martin F. Bach.

Part of the Progress in Nonlinear Differential Equations and Their Applications book series PNLDE, volume 36 Abstract In this chapter we show that low energy extremals concentrate at a single point and we analyze their local behaviour near the concentration point. Advancing research. Creating connections. This chapter discusses the solvability of nonlinear odd-ordered differential equations using K-monotonicity. It explains the existence of solutions to boundary value problems for nonlinear differential equations of the form LxNx = f, f ∈ H where H = L 2 [0,T], L is an odd-ordered ordinary differential operator, and N is a nonlinear.

equations to large systems of ordinary differential equations or stochastic ordinary differential equations. Consequently, the number of parameters is large and can easily reach thousands or more [Yang et al., 2018; Yang & Perdikaris, 2019]. With the enormous range of topics and vast literature now connected with variational inequalities, the subject has become part of the standard material taught in partial differential equations.

Journal de Mathématiques Pures et Appliquées 97:4, 318-390. Recent progress in the mathematical analysis of variational models for the plastic deformation of crystals in a geometrically nonlinear setting is discussed. The focus lies on the first time-step and on situations where only one slip system is active, in two spatial dimensions. The interplay of invariance under finite rotations and plastic deformation leads to the emergence of microstructures.

As it stands, the variational principle generates an exact, implicit equation for the stochastic phase. Here we carry out a perturbation expansion to show that the leading order dynamics of the phase over small time intervals recovers the.

Because of this, some modelers have added “noise terms” to their systems of equations by using so-called stochastic differential equations SDEs Meinhardt and De Boer, 2001; Chen et al. 2005. An alternative and widely-used approach to introducing stochasticity into a system of ODEs is to introduce a “master equation” derived from a.
