On the regularity of elasticity problems with piecewise analytic data. (English) Zbl 0790.35028
The authors present regularity results for solutions of plane elasticity in a polygon, in the frames of countably weighted Sobolev spaces introduced by the authors previously: the spaces of functions the weighted norms of whose derivatives are controlled by the series $$d^ k\cdot k!$$. These results are very useful for designing and analyzing the $$p$$ and $$h-p$$ version of the finite element solutions of the elasticity problems.
