Department of Mathematics, University of California, Santa Barbara, 2010. - 96 pages.
These lecture notes arose from the course "Partial Di erential Equations" - Math 124A taught by the author in the Department of Mathematics at UCSB in the fall quarters of 2009 and 2010. The selection of topics and the order in which they are introduced is based on Walter A. Strauss. Partial di erential equations. John Wiley & Sons Ltd., Chichester, second edition, 2008.
Most of the problems appearing in this text are also borrowed from Strauss. A list of other references that were consulted while teaching this course appears in the bibliography at the end.
