DESCRIPTION:The formalism of discrete differential forms has b
een used very successfully in computational electr
odynamics. It is based on the idea that only the o
bservables (i.e.\, the electromagnetic field) shou
ld be discretised and that coordinates should not
possess any relevance in the numerical method. Thi
s is reflected in the fact that Maxwell'\;s the
ory can be written entirely in geometric terms usi
ng differential forms. Einstein'\;s theory is e
ntirely geometric as well and can also be written
in terms of differential forms. In this talk I wil
l describe an attempt to discretise Einstein'\;
s theory in a way similar to Maxwell'\;s theory
. I will describe the advantages and point out dis
advantages. I will conclude with some remarks abou
t more general discrete structures on manifolds.
