(08:00 Los Angeles, 11:00 New York, 19:00 Moscow, 01:00 (next day) Tokyo)
we are pleased to have the talk

Title: Discrete gravity

Speaker: Slava Mukhanov (Munich U., ASC)

Abstract: We assume that the points in volumes smaller than an elementary 
volume (which may have a Planck size) are indistinguishable in any physical 
experiment. This naturally leads to a picture of a discrete space with a finite 
number of degrees of freedom per elementary volume. In such discrete spaces, 
each elementary cell is completely characterized by displacement operators 
connecting a cell to the neighboring cells and by the spin connection. We 
define the torsion and curvature of the discrete spaces and show that in the 
limiting case of vanishing elementary volume the standard results for the 
continuous curved differentiable manifolds are completely reproduced.
