# Mathematics Colloquium 2014-15

**Organiser:** Xue-Mei Li

Additional colloquia, titles and abstracts will be added as details become available.

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 of 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.
