There are many research groups in mathematics and statistics. Some researchers are members of more than one research group. This is not surprising since many mathematical fields are frequently necessary to solve a specific problem. Moreover, many of the seminars are joint seminars with the School of Mathematics and Statistics (Carleton University).
