Mean curvature flow for Lagrangian submanifolds with convex potentials

Zhang, Xiangwen, 1984- January 2008 (has links)
In recent years symplectic geometry and symplectic topology have grown to large subbranches in mathematics and had a great impact on other areas in mathematics. When interested in geometry, a geometer always considers geometric structures that arise on immersed submanifolds. In symplectic geometry there is a distinguished class of immersions, known as Lagrangian submanifolds . In particular, minimal Lagrangian submanifolds, called special Lagrangians, are very important in mirror symmetry. Lagrangian mean curvature flow is an important example of Lagrangian deformation. From which we can get the special Lagrangian submanifolds. In recent years, there have been many papers about this subject and the result by K.Smoczyk and Mu-Tao Wang [WS] is very important and beautiful. Our main purpose in this article is to give a new proof for the main result in [WS] from the viewpoint of fully nonlinear partial differential equations.

Representation of permutation operators in quantum mechanics

Seagraves, Paul Henry January 1964 (has links)
A simple method is presented for writing the matrix elements of transposition operators for discrete sets of quantum numbers. A proper product of these leads to easy computation of general permutation operators. It is shown how these operators may be constructed with operators defined in angular momentum space. Results agree with Dirac for transposition of two particles of spin ½ and with Kaempffer for spin 1. The calculations are performed to extend the results to spin 3/2 and 2 along with alternate representations. Special considerations are required for fermion creation and annihilation operators. / Science, Faculty of / Physics and Astronomy, Department of / Graduate
