نویسنده
چکیده
For variational inequalities of an abstract obstacle type, a comparison principle for the dependence of solutions on the constraint set K is used to provide a continuity estimate.

Is “teaching” an obstacle to “research”?
Introduction. Regarding the role of research in developing and improving a better culture, society and economics, 95% to 97% world finance in research belongs to developed countries while only 3%-5% to developing countries. Although the universities as the major organizations are to do research works, it seems that there are some problems to bring this true. We tried to find out if a load of t...
متن کاملRNA SYNTHESIS IN HELA CELLS Pattern in Hypertonic Medium and Its Similarity to Synthesis during G 2-Prophase THORU PEDERSON and ELLIOTT ROBBINS
Interphase HeLa cells manifest a stepwise shutoff of RNA synthesis when the tonicity of the extracellular medium is gradually increased . Synthesis of heterogeneous nuclear RNA is most sensitive and is selectively inhibited at 1 .5 times isotonicity (450 milliosmols/liter), while 45S ribosomal RNA synthesis is not affected significantly below 2 .0 times isotonicity . Transfer RNA synthesis is l...

متن کاملStability Results for Obstacle Problems with Measure Data
We study the convergence properties of the solutions of some elliptic obstacle problems with measure data, under the simultaneous perturbation of the operator, the forcing term and the obstacle. Stability results for obstacle problems with measure data 1
متن کاملMultigrid Methods for Obstacle Problems
Obstacle problems can be posed as elliptic variational inequalities, complementarity inequalities and Hamilton-Jacobi-Bellman (HJB) partial differential equations (PDEs). In this paper, we propose a multigrid algorithm based on the full approximate scheme (FAS) for solving the membrane constrained obstacle problems and the minimal surface obstacle problems in the formulations of HJB equations. ...
