Abstract

We consider smooth solutions to the biharmonic heat equation on Euclidean\nspace for which the square of the Laplacian at time t is globally bounded from\nabove by k/t for some k in R, for all t in [0,T]. We prove local, in space and\ntime, estimates for such solutions. We explain how these estimates imply\nuniqueness of smooth solutions in this class.\n
