Abstract
Nonexistence of global solutions to ultraparabolic equations and systems is presented.
Our results fill a gap in the literature on ultraparabolic equations. The
method of proof we use relies on a choice of a suitable test function in the weak
formulation of the solutions of the problems under-study.
