MATHEMATICS 435-PARTIAL DIFFERENTIAL EQUATIONS- FALL 2000

GOAL: This is an introductory course on linear PDEs at the senior undergraduate level;
the intended audience are students in mathematics, physics and engineering.  I will
emphasize analytical methods (kernel functions, Fourier series) and applications to the
classical PDEs of mathematical physics. The prerequisite for this course is  a working
knowledge of multivariable  calculus.

TIME/PLACE: Tuesday/Thursday, 5:05-6:20, Ayres 125

TEXT: Walter A. Strauss, Partial Differential Equations, J.Wiley (1992)

GRADING: Based on weekly homework assignments (20%), two in-class exams( 25% each)
and a comprehensive final exam (30%)

EXAM DATES: 9/28, 11/9; FINAL EXAM: 12/9, 5-7 p.m.

HOMEWORK- I will post on this web site  a list of problems from the
text for each section covered; some of these will be solved in class. The remaining problems
from the list will be collected each Thursday (at the beginning of class) and graded.
DUE DATE:  the problems due each Thursday are those in sections covered on the preceding
Tuesday and Thursday (usually 6 to 8 problems each week).
