Direct Reduction and Diierential Constraints
نویسنده
چکیده
Direct reductions of partial diierential equations to systems of ordinary diierential equations are in one-to-one correspondence with compatible diierential constraints. The diierential constraint method is applied to prove that a parabolic evolution equation admits innnitely many characteristic second order reductions, but admits a non-characteristic second order reduction if and only if it is linearizable.

Mechanical Systems Subject to Holonomic Constraints: Diierential-algebraic Formulations and Conservative Integration Mechanical Systems Subject to Holonomic Constraints: Diierential-algebraic Formulations and Conservative Integration
The numerical integration in time of the equations of motion for mechanical systems subject to holonomic constraints is considered. Schemes are introduced for the direct treatment of a diierential-algebraic form of the equations that preserve the constraints, the total energy, and other integrals such as linear and angular momentum arising from aane symmetries. Moreover, the schemes can be show...
متن کاملInvolution and Symmetry Reductions
After reviewing some notions of the formal theory of diierential equations we discuss the completion of a given system to an involutive one. As applications to symmetry theory we study the eeects of local solvability and of gauge symmetries, respectively. We consider non-classical symmetry reductions and more general reductions using diierential constraints.
متن کاملNecessary Optimality Conditions for Nonconvex Diierential Inclusion with Endpoint Constraints
In this paper, we derive necessary optimality conditions for optimization problems deened by non-convex diierential inclusions with endpoint constraints. We do this in terms of parametrizations of the convexiied form of the diierential inclusion and, under additional assumptions, in terms of the inclusion itself.
متن کاملA Precise Deenition of Reduction
We give a comprehensive analysis of interrelations between the basic concepts of the modern theory of symmetry (classical and non-classical) reductions of partial diierential equations. Using the introduced deenition of reduction of diierential equations we establish equivalence of the non-classical (conditional symmetry) and direct (Ansatz) approaches to reduction of partial differential equat...
متن کاملNumerical Analysis of Constrained Hamiltonian Systems and the Formal Theory of Differential Equations
We show how the formal theory of diierential equations provides a unifying framework for some aspects of constrained Hamiltonian systems and of the numerical analysis of diierential algebraic equations, respectively. This concerns especially the Dirac algorithm for the construction of all constraints and various index concepts for diierential algebraic equations. 1. Introduction Constrained Ham...
