摘要
This work is devoted to the study of the existence and approximation of solutions of the problem u " = f(t, u, u'), u'(a) = u'(b) = 0 in the presence of lower and upper solutions in the reverse order. To this end we prove anti-maximum principles for the nonlinear operator u " + 2k\u'\ + lambdau. (C) 2001 Elsevier Science Inc, All rights reserved.
