## Elliptic partial differential equations of second order. 2nd ed.(English)Zbl 0562.35001

Grundlehren der Mathematischen Wissenschaften, 224. Berlin etc.: Springer-Verlag. XIII, 513 p. DM 128.00; \$ 47.80 (1983).
In the second edition of this esteemed and useful exposition the authors made some minor revisions and added some material concerning recent developments of the theory. There are two additional chapters dealing with strong solutions of linear equations (L$${}^ p$$ theory, maximum principles and local properties of strong solutions) and the classical Dirichlet problem for fully nonlinear equations (Maximum and comparison principles, continuation method, interior estimates for second derivatives), respectively. Other chapters are supplemented by sections concerning capacity, Hölder estimates for the first derivatives, extension and interpolation of Sobolev spaces, the eigenvalue problem.
