Abstract: | We show that deletion of the loss part of the collision term in all physically relevant versions of the Boltzmann equation, including the relativistic case, will in general lead to blowup in finite time of a solution and hence prevent global existence. Our result corrects an error in the proof given (Math. Meth. Appl. Sci. 1987; 9 :251–259), where the result was announced for the classical hard sphere case; here we give a simpler proof which applies much more generally. Copyright © 2004 John Wiley & Sons, Ltd. |
