This website includes links to class notes and supplements (in PDF) used in the teaching of East Tennessee State University's senior/graduate level class Complex Variables (MATH 4337/5337). Links are also available for video presentations of the notes. The videos have been used as of the teaching of online Complex Variables, starting in spring 2020. The material is based closely on James Ward Brown and Ruel V. Churchill's Complex Variables and Applications, 8th Edition, McGraw-Hill (2009):

Brown and Churchill's Complex Variables with Applications book, 8th edition


Robert "Dr. Bob" Gardner can be reached by e-mail at: gardnerr@etsu.edu. His office is in Gilbreath Hall, Room 308F on the ETSU campus.


The following notes and supplements are all in PDF. They are housed on Google Drive and should be permanently available. No sign-in is required. The videos can be streamed from YouTube and should remain permanently available. (The videos previously on ETSU's Panopto host site have been, or may soon be, deleted.)
