Estimation of discontinuous coefficients in parabolic systems: Applications to reservoir simulation. (English) Zbl 0612.93014
A spline-based technique for the estimation of spatially varying parameters in parabolic systems is considered. In particular, it is allowed that the parameters are discontinuous. The method is restricted to the case of one space dimension.
