Discrete Mathematics at ISU (DISCMATH)
The Mathematics Department at Illinois State University (ISU) has a strong Discrete Mathematics Group. The group, usually called DISCMATH for brevity, is very active in research and professional service, as well as providing enthusiastic and dedicated teaching for students at master’s level and all undergraduate levels.
The DISCMATH group convenes a regular weekly seminar program, which runs throughout the Fall and Spring semesters and logs around 20-30 talks each academic year. Meetings last 50 minutes, followed by a 20 minutes informal social gathering. Most talks report on recent results or research in progress, but occasional expository and survey talks are included. Speakers usually are ISU faculty members of DISCMATH, but also include graduate students, invited speakers from other institutions, and visitors to the ISU Mathematics Department (often the Department hosts one or more longer term visitors in Discrete Mathematics).
Discrete Mathematics Seminar
For the Fall 2018 semester, the talks are given on Thursdays, 2:00 p.m.-2:50 p.m., in Stevenson Hall (Room STV 136B). Immediately after the seminar, all participants are invited to room 313 D in Stevenson Hall for 20 minutes of social get-together, coffee or tea, and cookies. Follow the links below for further information on specific talks. If you want to give a talk, please send an email to mbahman[at]ilstu[dot]edu.
