Elliptic Partial Differential Equations

This volume is based on PDE courses given by the authors at the Courant Institute and at the University of Notre Dame (IN). Presented are basic methods for obtaining various a priori estimates for second-order equations of elliptic type with particular emphasis on maximal principles, Harnack inequalities, and their applications. The equations considered in the book are linear, however, the presented methods also apply to nonlinear problems.Han, Qing is the author of 'Elliptic Partial Differential Equations' with ISBN 9780821826911 and ISBN 0821826913.
