EC HUMAN CAPITAL AND MOBILITY SCHEME


NETWORK - ANALYTICAL AND NUMERICAL INVESTIGATION OF RANDOM GEOMETRIES: FROM INTERFACES TO QUANTUM GRAVITY


The European Commission provided funding as part of the Human Capital and Mobility scheme to support for the three year period December 1993- December 96 a network of universities and research laboratories which were involved with research in the the general field of the statistical mechanics of random surfaces and manifolds.

Three plenary meetings, in Paris in May 1994 in Reykjavik in January 1995 and in Edinburgh in September 1995 provided excellent forums for the exchange of ideas among network members.


The behaviour of random surfaces is of interest in many areas of physics and mathematics, ranging from the properties of cell membranes to string theory and quantum gravity. In simulations smooth surfaces are approximated by triangulations and the fluidity is incorporated by allowing changes in connectivity.


The network was made up of the following sites:
