Abstract:
We consider an optimal sufficient condition for the existence of solutions to the critical semilinear heat equation by introducing uniformly local weak Zygmund type spaces. Differences between standard (weak) Zygmund spaces and the space introduced here will be explained by focusing several properties for the heat semigroup in these spaces.
