Isac, G.; Li, Jinlu Complementarity problems, Karamardian’s condition and a generalization of Harker-Pang condition. (English) Zbl 1002.90073 Nonlinear Anal. Forum 6, No. 2, 383-390 (2001). Summary: We present some existence theorems for nonlinear complementarity problems in Hilbert spaces. Our results are related to Karamardian condition and Harker-Pang condition. We put in evidence some aspects related to the both conditions.
