Introduction
Cape Town Research Group in Topology and Category Theory


The Cape Town Research Group in Topology and Category Theory traces its origins back almost 30 years to the early activities in Categorical Topology at the University of Cape Town. Under the leadership of Professors Keith Hardie and Guillaume Brümmer the group established itself as an international centre of research in categorical topology and bi-topology. A long-time association with Professor Bernhard Banaschewski (McMaster University, Canada) has seen the development of a strong school in frame (locale) theory within the research group.

The group presently has 8 full members and a number of graduate students. Members' affiliations, and the group's activities, extend to the Universities of Cape Town, Stellenbosch and the Western Cape.

Our present research interests cover category theory, categorical topology, (asymmetric) general topology, frame (locale) theory, differential geometry and homotopy theory.

In the past few years we also lost two of our members, Prof Paul Cherenack (17.01.2002) and Dr Japie Vermeulen (11.02.2001). Tributes to Paul and Japie can be viewed here.

A happier occasion was the recent highlight of the award of an honourary doctorate to our long-time collaborator, Prof Bernhard Banaschewski.

From this site you can access information about our members, our seminars and other activities, as well as download a selection of recent preprints. Should you wish to know more about interacting with the Research Group please feel free to contact us.
