We especially analyze constraints which depend on restriction on subsets of positive measure and on the trace on a portion of the boundary. 2000 Mathematics Subject Classification: 26D15; 35R45, 74B05.

Web3 Korn’s inequality We would like to prove existence of a solution. In order to do that we’d like to establish whether the form a(u,v) is coercive. This can be proved using Korn’s inequality. Twierdzenie 1 (Korn’s inequality). Let Ω be a bounded set with regular bo-undary1. There exists a constant C>0 (dependent on Ω) such that Z Ω ... WebRemark 3. Since (8) reduces to the classical Korn's inequality (5) when uk = u is independent of k, it follows that the optimal constants a in (8) and (5) are the same. I am grateful to Roger L. Fosdick for informing me about the Korn's inequality and to Richard D. James for many useful discussions and suggestions. I thank John M. Ball for showing isf portal
