Mathematics of Operations Research, Vol. 20, No. 4 (Nov., 1995), pp. 818-837 (20 pages) A nonlinear extension of Farkas' lemma for systems involving the difference of sublinear functions is presented.

Several factors imply an increase in the use of nonlinear optimization models. We face serious problems of declining productivity and increasingly scarce, expensive raw materials. Computers are ...

Nonlinear optical crystals are a class of materials that exhibit unique properties when interacting with light. Unlike conventional optical materials, which respond linearly to the electric field of ...
