# Mathematics Colloquium

## Summer Term 2008-09

Organiser: Volker Betz (V dot M dot Betz at warwick dot ac dot uk) and Brian Bowditch ()

Additional colloquia, titles and abstracts will be added as details become available. ( pdf of poster)

Colloquia take place on Friday afternoons at 4.00pm, Lecture Room B3.02 in the Mathematics Institute, Zeeman Building. They are directed towards a general mathematical audience. In particular, one the functions of these Colloquia is to inform non-specialists and graduate students about recent trends, ideas and results in some area of mathematics, or a closely related field.
