We consider a non-linear heat equationposed on thed-dimensional torus, wherePis a polynomial of degree at most 3 andBis a bilinear map that is not a total derivative. We show that, if the initial conditionis taken from a sequence of smooth Gaussian fields with a specified covariance, thenuexhibits norm inflation with high probability. A consequence of this result is that there exists no Banach space of distributions which carries the Gaussian free field on the 3D torus and to which the DeTurck–Yang–Mills heat flow extends continuously, which complements recent well-posedness results of Cao–Chatterjee and the author with Chandra–Hairer–Shen. Another consequence is that the (deterministic) non-linear heat equation exhibits norm inflation, and is thus locally ill-posed, at every point in the Besov space; the spaceis an endpoint since the equation is locally well-posed forfor every.
