Under common conditions, we have claimed the existence of equilibrium in incomplete security-spot market with a continuum of traders. Because of the development from complete market to incomplete market, we have not only generalized Aumann＇s results in 1966, but also achieved a breakthrough on researching methods.展开更多

The authors establish the local existence and uniqueness of the weak solution to the heat flow for the Yang-Mills-Higgs field in a vector bundle over a compact Riemannian 4-manifold, and show that the weak solution is gauge-equivalent to a smooth solution and there are at most finite singularities at the maximum existing time.展开更多

The first was the reversal from the ＂metaphysics of presence＂ represented by Platonism to the ＂metaphysics of subjectivity＂ represented by Descartes, Kant and Hegel. The second occurred within the framework of the metaphysics of subjectivity and marked the transformation from the ＂metaphysics of reason＂ represented by Descartes, Kant and Hegel to the ＂metaphysics of will＂ represented by Schopenhauer and Nietzsche. The third reversal was from the ＂metaphysics of being-there＂ of the earlier phase of Hcidegger＇s philosophy to his later ＂metaphysics of the world-fourfold.＂展开更多
