✦ Synopsis


Using a new method, we generalize the blow up and existence result from P. Baras and J. A. Goldstein (1984, Trans. Amer. Math. Soc. 284, 121-139) to heat equations on the Heisenberg group. In doing so we need to overcome the difficulty that the equation in this case is both degenerate and of variable coefficients. Comparing with the Euclidean case, an interesting new result is that solutions can blow up even when the singularity of the potential is weaker than the inverse square of the distance function.

## Abstract It is shown that the Cauchy problem in ℝ for the strongly degenerate parabolic equation has a nonnegative weak solution for any nonnegative bounded continuous initial datum, provided that __q__ ≀ __p__ – 1, while there is no (continuous) weak solution for __q__ > __p__ – 1. The evoluti
