Abstract:
This article concerns the question of uniqueness in the identification
of coefficients in a one-dimensional parabolic partial differential equation.
The solution of an initial-boundary value problem is observed at one
internal point over a finite time interval. It is shown that, under the
condition that the coefficient is known a priori on a subinterval, the
coefficient on the entire interval is uniquely determined by such observation.
