(Existence and uniqueness for the model problem for a plate–beam system was proved in Van Rensburg et al., ) Returning to FEM convergence: most of the articles we studied were published after and about half after Author: N F J van Rensburg, B Stapelberg. Existence and Uniqueness of Solutions to a Long Range Diﬀusive Predator-Prey Model Marwan S. Abualrub Department of Mathematics, University of Jordan P.O.

The model with a awas invented in [8] and, as explained therein (see also [6],[7]) is purported to describe the dynamic evolution of a price p(t) as in uenced by a population of buyers and sellers. In this initial reference, the existence of solutions was discussed, mostly in the context of a non{compact domain. Existence and uniqueness of solutions (optional): For iterative or optimization problems, in cases where the existence or uniqueness of a solution has been demonstrated by analytical means, a description may be presented. Tests from different initial value conditions should be conducted to provide evidence of the uniqueness of solutions. THE EXISTENCE AND UNIQUENESS OF SOLUTIONS TO DIFFERENTIAL EQUATIONS JAMES BUCHANAN Abstract. I expound on a proof given by Arnold on the existence and unique-ness of the solution to a rst-order di erential equation, clarifying and expand-ing the material and commenting on the motivations for the various compo-nents.

6. Conditions for existence and uniqueness of the solution to real-valued, non-homogeneous Sturm-Liouville problems In the present section we assume problems with real coeﬃcients. Equa-tions with complex coeﬃcients can be split into the real and the imaginary parts. Existence of eigenvalues for real-valued Sturm-Liouville prob-lems. Resources for United States.

Existence and uniqueness of the solution We are going to prove the existence and uniqueness of the solution to the above problem under the assumption that ε > 0 for all t. To this end we note that problem () + () without loss of generality can be reduced in two steps to one of the same kind where C, ε are by: 2. Lecture 5 - Existence and uniqueness of solutions In this lecture, we brieﬂy discuss two key questions in the ﬁeld of diﬀerential equations. Question: (Existence) Does every diﬀerential equation with an initial condition have a solution? Answer 1: Deﬁnitely not! Example: (y0)2 +y2 +1 = 0 cannot have a solution! Do you see why?
