This annual lecture series honors the memory of Professor Waldemar J. Trjitzinsky who came to the United States from Russia, and taught and researched in the Department of Mathematics at the University of Illinois from 1934 to 1969. The lecture series began in 1978 and was made possible from the gifts of Trjitzinsky's former Ph.D. students; Bing K. Wong, one of Trjitzinsky's students was the person responsible for setting up the Trjitzinsky fund. Each series of three lectures is aimed at a general mathematical public and graduate students.
