Backward uniqueness for parabolic operators with non-Lipschitz coefficients
Backward uniqueness for parabolic operators with non-Lipschitz coefficients
In this paper we study the backward uniqueness for parabolic equations with non-Lipschitz coefficients in time and space. The result presented here improves an old uniqueness theorem due to Lions and Malgrange [Math. Scand. 8 (1960), 277–286] and some more recent results of Del Santo and Prizzi [J. Math. Pures …
