existence and bifurcation of integral manifolds with applications

Science China Mathematics 2005年第7期48卷 940-957页

作者： HAN Mao'an CHEN Xianfeng Department of Mathematics Shanghai Normal University Shanghai 200234 China Department of Mathematics Shanghai Jiao Tong University Shanghai 200030 China

In this paper a bifurcation theorem on the existence of integral manifolds is obtained by using contracting principle. As an application, sufficient conditions for a higher dimensional system to have an integral manifold are given. Especially the existence and uniqueness of a 3-dimensional invariant torus appearing in a 4-dimensional autonomous system with singularity of codimension two are proved.

The Cauchy problem for non-autonomous nonlinear Schr(o)dinger equations

引用

Science China Mathematics 2005年第4期48卷 522-538页

作者： Peter Y. H. Pang Department of Mathematics

In this paper we study the Cauchy problem for cubic nonlinear Schr(o)dinger equation with space-and time-dependent coefficients on Rm and Tm. By an approximation argument we prove that for suitable initial values, the Cauchy problem admits unique local solutions. Global existence is discussed in the cases of m=1,2.

关键词： non-autonomous Schr(o)dinger equations, local existence, global existence.

The Philosophical Discourse of Being: Confucianism, Daoism, and Buddhism in A Dream of Red Mansions

引用

孔学堂 2016年第3期 5-20页

作者： Chen Xunwu Ph.D. Professor of PhilosophyDepartment of Philosophy & ClassicsThe University of Texas at San AntonioSan AntonioTX 78249USA

This essay offers a philosophical reading of the Chinese literary masterpiece A Dream of Red Mansions, which is a classic of both literature and philosophy. The philosophy of the novel captures the essential wisdom of traditional Chinese philosophies and illustrates the universality of the philosophical truths of humanity. The novel expounds a monumental phenomenology of humanity, and its philosophical questions, insights, profound vision and horizon of humanity constitute a universal paradigm for studying humanity and human existence.

The existence of the lunar has its advantages as well as disadvantages. Many dynamic phenomena are related to the lunar due to the rate of masses of the earth and the lunar is maximum. That is probably the reason for the life existence on the earth. The tide resulted from the moon gravitational force is the root of some disasters. However, it can also reduce the green house effect and regulate the temperature. It is proved that the moon is the thermostat of the earth. The greenhouse effect would be out of control without the moon, and the tendency for the global warming up would be critical. It is a risk to smash the moon without understanding clearly the advantage and disadvantage.

关键词： the moon, tide, global warming, El Nino, life existence, greenhouse effect
