Ch. Lin et Le. Payne, ON THE SPATIAL DECAY OF ILL-POSED PARABOLIC PROBLEMS, Mathematical models and methods in applied sciences, 3(4), 1993, pp. 563-575
This paper investigates the spatial decay of solutions to two ill-pose
d parabolic initial-boundary value problems: 1) the backward heat equa
toin defined on a semi-infinite cylinder in R(N) and 2) the backward S
tokes flow equations defined on a semi-infinite strip in R2.
