## What is Seminar?

The Mathematics Program has two seminars: The Undergraduate Mathematics Seminar, and the Graduate Mathematics Seminar. The seminars consist of invited lectures on contemporary mathematics and applications of mathematics to other areas of study and life. Topics have included mathematics education, physics, mathematics research, and interdisciplinary applications of mathematics, like biological and ecological mathematical modeling.

The Undergraduate Mathematics Seminar is held during Math 499: Senior Colloquium, 4:30-5:20PM, on certain days (see the schedule below). The Math 599: Graduate Mathematics Seminar is held every Monday 6:00-7:00PM. Because of the Covid-19 pandemic, seminar talks will be done virtually. **All mathematics students and faculty will obtain the Zoom links and passwords internally via email. If you need the link, **please email Dr. Alona Kryshchenko at alona.kryshchenko@csuci.edu for the graduate seminar (Math 599) and Dr. Ivona Grzegorczyk at ivona.grzegorczyck@csuci.edu for the undergraduate seminar (Math 499). Please see check back periodically. Everyone is invited to attend!

The Undergraduate Mathematics Seminar is sponsored by Instructional Related Activities Funds.

### What are the strengths of this series?

The seminars give our students the opportunity to see math at work. There is a good portion of our enrolled undergraduates that are interested in teaching. While we make sure to bring in speakers that discuss mathematics education, we also want our students to experience other fields. We do so by exposing them to the careers in mathematical research, academia, and industry via our speakers. Our students have the opportunity to follow up with the speakers if they wish, thus widening their network.
