The New York Group Theory Cooperative was founded many years ago. It grew out of the New York Group theory Seminar and the very generous support from the National Science Foundation in the development of an innovative graphically driven group-theoretical software package Magnus. This was named after one of the founders of group theory, Wilhelm Magnus, whose picture is attached here. Have a look at its history, below. For many years the New York Group Theory Seminar was coordinated by Gilbert Baumslag.
New York Group Theory Seminar: The seminar meets Friday 4:00-5:00 p.m. at the Graduate Center of the City University of New York (Room 5417 or 4201). The current organizers are Sean Cleary, Olga Kharlampovich, Alexei Miasnikov and Vladimir Shpilrain.
