Recession cones and the domination property in vector optimization

This paper presents a study of recession cones of nonconvex sets in infinite dimensional spaces. The results are then applied to investigate efficiency conditions and the domination property in vector optimization.This paper was written when the author was at the University of Erlangen-Nürnberg under a grant of the Alexander von Humboldt-Stiftung.On leave from the Institute of Mathematics, Hanoi, Vietnam.
