Abstract

<p/> <p>A generalization of the well-known Hartman&#8211;Nagumo inequality to the case of the vector ordinary <inline-formula><graphic file="1029-242X-2002-785482-i2.gif"/></inline-formula>-Laplacian and classical degree theory provide existence results for some associated nonlinear boundary value problems.</p
