    Course outline

    Instructor: Dr. Gantumur Tsogtgerel

    Prerequisite: MATH 580 (PDE1), MATH 355 (Honours Analysis 4) or equivalent

    Note: If you plan to take this course without taking MATH 580, please consult with the instructor.

    Topics: After covering some topics related to the heat equation and the Cauchy-Kovalevskaya theorem, the main focus of the course is going to be on the theory of distributions, general constant coefficient operators, semilinear evolution equations, and strongly elliptic systems. The approach will be from the viewpoint of a general theory, rather than as apparently ad hoc treatments of specific examples. As such, distributions, the Fourier transform, and functional analytic methods will be heavily used. More precisely, the planned topics are

  • The heat equation: maximum principles, the heat kernel, uniqueness theorems
  • Nirenberg-Nishida, Cauchy-Kovalevskaya, and Holmgren theorems
  • Distributions, convolution, Fourier transform
  • Constant coefficient operators, fundamental solution, hypoellipticity
  • Malgrange-Ehrenpreis theorem
  • Hörmander's characterization of hypoelliptic polynomials
  • Introduction to wave front sets, microlocal regularity
  • Problems in half-space, shades of hyperbolicity, parabolicity, and ellipticity
  • Fourier analytic treatment of Sobolev spaces
  • Semilinear evolution equations, Duhamel's principle
  • The Navier-Stokes equations
  • Overview of elliptic theory, Lopatinsky-Shapiro condition
  • Strongly elliptic systems, Gårding inequality
  • Elliptic regularity
  • Introduction to pseudodifferential operators (if time permits)
  • Semilinear elliptic problems with critical exponents (if time permits)

    Calendar description: Systems of conservation laws and Riemann invariants. Cauchy-Kowalevskaya theorem, powers series solutions. Distributions and transforms. Weak solutions; introduction to Sobolev spaces with applications. Elliptic equations, Fredholm theory and spectra of elliptic operators. Second order parabolic and hyperbolic equations. Further advanced topics may be included.

    Books: There is no required textbook. The followings are recommended.

  • Gerald Budge Folland, Introduction to partial differential equations. Princeton 1995.
  • Gregory Il'ich Eskin, Lectures on linear partial differential equations. AMS 2011.
  • Joseph Theodor Wloka, Partial differential equations. Cambridge 1987.

    Homework: Assigned and graded roughly every other week.

    Weakly seminars: We will organize weekly seminars on standard results from analysis and geometry, and other stuff related to the course.

    Course project: The course project consists of the student reading a paper or monograph on an advanced topic, typing up notes, and giving a lecture.

    Grading: The final grade will be the weighted average of homework 20%, the take-home midterm exam 30%, and the course project 50%.
