The Caltech Math Club provides an arena for undergraduate students, graduate students, and postdoctoral fellows to discuss research in the mathematical sciences. Membership is open to all members of the Caltech community, including undergraduates and graduate students from all disciplines. We occasionally invite guest speakers to present on new developments in the mathematical sciences or to give expository presentations on more well-established subjects at our seminars. We also help run the Caltech Harvey Mudd Math Competition.
