We establish a strong maximum principle for a nonnegative continuous solution u: Ω¯×[0, T)→ R+ of a doubly nonlinear parabolic problem in a space–time cylinder Ω×(0, τ) with a domain Ω⊂ R N and a sufficiently short time interval (0, τ)⊂(0, T). Our method takes advantage of a nonnegative subsolution derived from an expanding spherical wave.
