Abstract
Existence and uniqueness are proved for nonlocal (in time) for
solutions of linear parabolic partial differential equations. Instead of an
initial condition, there is a relation connecting the initial value to values
of the solution at other times. L2 error estimates are obtained for the
semidiscrete approximation of the problem using finite elements in the
space variables.
