The XVIIIth Oporto Meeting on Geometry, Topology and Physics will take place in Oporto, Portugal, from July 9th to 12th, 2009 (Thursday to Sunday). The aim of the Oporto Meetings is to bring together mathematicians and physicists interested in the inter-relation between geometry, topology and physics and to provide them with a pleasant and informal environment for scientific interchange. The web pages of previous meetings can be found at: OM.

As in previous years, the meeting is focussed on the short courses given by the main speakers, which are supplemented by seminars by other participants. The talks are at the advanced graduate or postdoctoral level, and should be of interest to all researchers wishing to learn about recent developments in the overlap between geometry, topology and physics.
