On the absence of rapidly decaying solutions for parabolic operators whose coefficients are non-Lipschitz continuous in time
We find minimal regularity conditions on the coefficients of a par- abolic operator, ensuring that no nontrivial solution tends to zero faster than any exponential
Parabolic operator, rapidly decaying solution, modulus of continuity, Osgood condition.
