The exchange of ideas plays a central role in the advancement of the mathematical sciences. For this reason, the department sponsors a vigorous program of research seminars, colloquium speakers, and visiting scholars.

Research Seminars

Research seminars focus on currently developing ideas, and allow participants (both graduate students and faculty) to become actively involved in ongoing research. Recent seminar topics have included analysis, approximation, set theory and topology, discrete mathematics, computational complexity, and commutative algebra.

Colloquia

The department's colloquium series brings in several speakers from outside the University each month. They usually present some of their most recent research. Many mathematicians of world renown have been colloquium speakers during the last few years. Recent speakers include:

• Peter G. Casazza, University of Missouri
• Alexander Bobylev, Keldysh Institute of Applied Mathematics, Academy of Sciences, Moscow
• Nigel Kalton, University of Missouri
• Lars Andersson, Royal Institute of Technology, Sweden
• Farhad Shahrokhi, University of North Texas
• Gyula Katona, Mathematical Institute of the Hungarian Academy of Sciences
• Péter L. Erdös, Mathematical Institute of the Hungarian Academy of Sciences
• Dmitriy B. Silin, Lawrence Berkeley National Laboratory and Moscow State University
• Geng Xu, Johns Hopkins University
• Alexandre B. Tchernev, Purdue University
• Erich Novak, University of Erlangen, Germany

Visiting Scholars

The department regularly hosts visiting scholars from other institutions. They generally stay for one or more semesters, and are involved in the graduate program either through teaching graduate courses or participation in seminars.

Recent visitors with teaching responsibilities include:

• Rostom Getsadze ( rostom )
• Sergei Konyagin ( konyagin )
• Denka Kutzarova ( denka )
