Existence Results for a Dirichlet Quasilinear Elliptic Problem
In this paper, existence results of positive classical solutions for a class of second-order differential equations with the nonlinearity dependent on the derivative are established. The approach is based on variational methods.
متن کاملA Novel Interactive Possibilistic Mixed Integer Nonlinear Model for Cellular Manufacturing Problem under Uncertainty
Elaborating an appropriate cellular manufacturing system (CMS) could solve many structural and operational issues. Thereby, considering some significant factors as worker skill, machine hardness, and product quality levels could assist the companies in current competitive environment. This paper proposes a novel interactive possibilistic mixed integer nonlinear approach to minimize the total co...
متن کاملMixed Multiscale Methods for Heterogeneous Elliptic Problems
We consider a second order elliptic problem written in mixed form, i.e., as a system of two first order equations. Such problems arise in many contexts, including flow in porous media. The coefficient in the elliptic problem (the permeability of the porous medium) is assumed to be spatially heterogeneous. The emphasis here is on accurate approximation of the solution with respect to the scale o...
متن کاملMixed Finite Element Methods for Elliptic Problems*
This paper treats the basic ideas of mixed finite element methods at an introductory level. Although the viewpoint presented is that of a mathematician, the paper is aimed at practitioners and the mathematical prerequisites are kept to a minimum. A classification of variational principles and of the corresponding weak formulations and Galerkin methods—displacement, equilibrium, and mixed—is giv...
متن کاملTrial Methods for a Nonlinear Bernoulli Problem Trial Methods for a Nonlinear Bernoulli Problem
In this work we consider the problem of determining the free surface for a stationary ow of inviscid uid. We introduce several diierent formulations for the problem and study the numerical methods suggested by diierent formulations. The formulations to be studied include 'shape varia-tional principles' where free boundary is sought after as a critical point of a 'shape' energy functional, as we...
