Ricci flow on K\"ahler-Einstein manifolds

Author(s) : Chen, X. X. , Tian, G.
Description : In our previous paper math.DG/0010008, we develop some new techniques in attacking the convergence problems for the K\"ahler Ricci flow. The one of main ideas is to find a set of new functionals on curvature tensors such that the Ricci flow is the gradient like flow of these functionals. We succes...

The K\"ahler-Ricci flow on K\"ahler manifolds with 2 traceless bisectional curvature operator

Author(s) : Chen, X. X. , Li, H.
Description : It was proved by H. Chen earlier that the property of the sum of any two eigenvalues of the curvature operator is positive is preserved under the ricci flow in all dimensional. By a recent result of Phong-Sturm, a similar notion of positive 2-traceless bisectional curvature positive is preserved o...

Geometry of K\"ahler Metrics and Foliations by Holomorphic Discs

Author(s) : Chen, X. X. , Tian, G.
Description : The purpose of this paper is to establish a completely new partial regularity theory on certain homogeneous complex Monge-Ampere equations. Our partial regularity theory will be obtained by studying foliations by holomorphic curves and and their relations to homogeneous complex Monge-Ampere equati...

Boltzmann Distribution and Temperature of Stock Markets

Author(s) : Kleinert, H. , Chen, X. J.
Description : The minute fluctuations of of S&P 500 and NASDAQ 100 indices display Boltzmann statistics over a wide range of positive as well as negative returns, thus allowing us to define a {\em market temperature} for either sign. With increasing time the sharp Boltzmann peak broadens into a Gaussian whose v...

Evolution of Supermassive Black Hole Binary and Acceleration of Jet Precession in Galactic Nuclei

Author(s) : Liu, F. K. , Chen, X.
Description : Supermassive black hole binary (SMBHB) is expected with the hierarchical galaxy formation model. Currently, physics processes dominating the evolution of a SMBHB are unclear. An interesting question is whether we could observationally determine the evolution of SMBHB and give constraints on the ph...

Optical conductivity of a metal-insulator transition for the Anderson-Hubbard model in 3 dimensions away from 1/2 filling

Author(s) : Chen, X. , Gooding, R. J.
Description : We have completed a numerical investigation of the Anderson-Hubbard model for three-dimensional simple cubic lattices using a real-space self-consistent Hartree-Fock decoupling approximation for the Hubbard interaction. In this formulation we treat the spatial disorder exactly, and therefore we ac...

Primordial Binary Evolution and Blue Stragglers

Author(s) : Chen, X. , Han, Z.
Description : Blue stragglers have been found in all populations. These objects are important in both stellar evolution and stellar population synthesis. Much evidence shows that blue stragglers are relevant to primordial binaries. Here, we summarize the links of binary evolution and blue stragglers, describe t...

Conflict-Directed Backjumping Revisited

Author(s) : Chen, X. , van Beek, P.
Description : In recent years, many improvements to backtracking algorithms for solving constraint satisfaction problems have been proposed. The techniques for improving backtracking algorithms can be conveniently classified as look-ahead schemes and look-back schemes. Unfortunately, look-ahead and look-back sc...
