Seminar Series

The ORCAS seminar series, established in Fall 2006, has roots in the history of departmental research, and represents a continuation of seminars run over the last decades. We note the previous "Optimization, Dynamical Systems and Applied Analysis" (2000-2006) seminars, the "Complex Systems" seminars (1991-1999) and the numerous events in dynamical systems taking place with departmental involvement.
