The long awaited second edition of this very successful textbook for graduate students covers the study of first and second order of Partial Differential Equations. This may also be used by persons preparing for CSIR/UGC, GATE and UPSC examinations. New to this edition: improved presentation; additional exercises and worked examples at the end of each section with solutions; and also useful for students of Engineering and Physics.
