Weakly Elliptic Systems with Obstacle Constraints: Part Iii { Complex Eigenvalues and Singular Systems
Using traditional methods, especially that of eigenfunction expansions combined with the penalty method, sharp conditions are given for the existence of solutions to a general weakly elliptic linear N N second order systems subjected to obstacle type constraints. The result applies to systems with deening coeecient matrices A and B having complex eigenvalues as well as to the case of singular s...
متن کاملNonlinear weakly elliptic 2 × 2 systems of variational inequalities with unilateral obstacle constraints ∗
We study 22 systems of variational inequalities which are only weakly elliptic; in particular, these systems are not necessarily monotone. The prototype diierential operator is the (vector-valued) p-Laplacian. We prove, under certain conditions, the existence of solutions to the unilateral obstacle problem. In addition, we address the question of determining function spaces on which the p-Lapla...
متن کاملSingular constrained linear systems
In the linear system Ax = b the points x are sometimes constrained to lie in a given subspace S of column space of A. Drazin inverse for any singular or nonsingular matrix, exist and is unique. In this paper, the singular consistent or inconsistent constrained linear systems are introduced and the effect of Drazin inverse in solving such systems is investigated. Constrained linear system arise ...
متن کاملWeakly Coupled Elliptic Systems and Positivity
In this paper we will study under which conditions the positive cone, or part of the positive cone, is preserved when solving a weakly coupled system of elliptic partial differential equations. Such a system will be as follows: −∆1 0 0 . . . 0 0 −∆k u1 .. uk = c11 · · · c1k .. .. ck1 · · · ckk u1 .. uk + f1 .. fk on a bounded domain in IR, with zero Dirichlet bounda...
متن کاملConvergence of product integration method applied for numerical solution of linear weakly singular Volterra systems
We develop and apply the product integration method to a large class of linear weakly singular Volterra systems. We show that under certain sufficient conditions this method converges. Numerical implementation of the method is illustrated by a benchmark problem originated from heat conduction.
