We prove that an antimaximum principle holds for the Neumann and Dirichlet periodic parabolic linear problems of se cond order with a time periodic and essentially bounded weight functio n. We also prove that an uniform antimaximum principle holds for the on e dimensional Neumann problem which extends the corresponding ell iptic case.
