Course Description
 A partial differential equation (PDE) is an equation that contains unknown multivariable functions and their partial derivatives. PDEs can be used to describe a wide variety of phenomena such as sound, heat, electrostatics, electrodynamics, fluid flow, elasticity, or quantum mechanics. In this course, we will address many of the mathematical issues on various types of PDEs. We will also discuss boundary value problems on PDE, and related applications in physics and other natural sciences. A brief outline of topics to be covered is as follows.
 List of Topics:
 An introduction to PDEs and associated applications.
 Firstorder linear and nonlinear PDE:
 Linear transport equations, the Burgers equation, and other firstorder nonlinear PDE.
 Local existence theory on initial/boundary value problems of firstorder PDE.
 Method of characteristics.  Secondorder linear PDE, 3 basic equations:
 The wave equation and the heat equation (diffusion).
 Boundary conditions, the Fourier method.
 The Laplace equation: fundamental solution, Green's function in unbounded and bounded domains.  Other selected topics will be covered if time permits.
Online Lectures
 Due to the coronavirus pandemic, online lectures will be offered via Blackboard Collaborate Ultra. You can access the virtual classroom from the course page at Blackboard (Click "Online Lectures") at normal lecture time. A microphone is recommended for inclass communication. Lectures will be recorded for future access.
 Office hours will also be offered via the internet. A session has been created in the Blackboard system. Other than the regular office hours, appointments can be made via email.

Homework Assignments
 Homework assignments will be assigned via blackboard and collected each week. The tentative due date is on Tuesday at 2pm.
 The homework is not pledged. You are encouraged to discuss the problems. However, each student is responsible for the final preparation of his/her own homework papers.

Exams
 There will be a 75 minutes takehome midterm exam. The date will be announced later (at least 10 days before the exam is released). There will be a 150 minutes takehome cumulative final exam.
 In both exams, you can use the textbook, your own lecture notes, and your own homework assignments. Other communications and help are not allowed.
