In this thesis, we consider the following two important subjects in the modern variational analysis for the corresponding nonconvex/nonmonotone and nonsmooth cases: geometric results and the variational inequality problem. By using the variational technique, we first present several nonsmooth (nonconvex) geometric results (including an approximate projection result, an extended extremal principle, nonconvex separation theorems, a nonconvex generalization of the Bishop-Phelps theorem and a separable point result) which extend some fundamental theorems in linear functional analysis, convex analysis and optimization theory. Then, by transforming the variational inequality problem into equivalent optimization problems, we establish some error bound result for the nonsmooth and nonmonotone variational inequality problem. / Variational arguments are classical techniques whose use can be traced back to the early development of the calculus of variations. Rooted in the physical principle of least action they have evolved greatly in connection with applications in optimization theory and optimal control. Recently, the discovery of modern variational principles and nonsmooth analysis further expand the range of applications of these techniques and give a new way for extending some geometric results in linear functional analysis and convex analysis. / Li, Guoyin. / "August 2007." / Adviser: Kung-Fu Ng. / Source: Dissertation Abstracts International, Volume: 69-02, Section: B, page: 1043. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2007. / Includes bibliographical references (p. 80-86). / Electronic reproduction.
