the algorithm for solving the inverse numerical range problem
برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
15 صفحه اولIsovector neutron-proton pairing with particle number projected BCS
The particle number projected BCS (PBCS) approximation is tested against the exact solution of the SO(5) Richardson-Gaudin model for isovector pairing in a system of nondegenerate single-particle orbits. Two isovector PBCS wave functions are considered. One is constructed as a single proton-neutron pair condensate; the other corresponds to a product of a neutron pair condensate and a proton pai...
متن کاملA Projected Gradient Algorithm for Solving the Maxcut Sdp Relaxation∗
In this paper, we develop a specialized algorithm for solving the semidefinite programming (SDP) relaxation of the maximum cut (maxcut) problem. The maxcut problem has many applications, e.g., in VLSI design and statistical physics (see [2, 4, 5, 19, 21]). Several algorithms have been proposed to find either exact or approximate solutions to this problem. As for many combinatorial optimization ...
متن کاملThe Projected Single-Particle Dirac Operator for Coulombic Potentials
A sequence of unitary transformations is applied to the one-electron Dirac operator in an external Coulomb potential such that the resulting operator is of the form Λ+AΛ+ + Λ−AΛ− to any given order in the potential strength, where Λ+ and Λ− project onto the positive and negative spectral subspaces of the free Dirac operator. To first order, Λ+AΛ+ coincides with the Brown-Ravenhall operator. Mor...
متن کاملThe smoothed particle hydrodynamics method for solving generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system
A meshless numerical technique is proposed for solving the generalized variable coefficient Schrodinger equation and Schrodinger-Boussinesq system with electromagnetic fields. The employed meshless technique is based on a generalized smoothed particle hydrodynamics (SPH) approach. The spatial direction has been discretized with the generalized SPH technique. Thus, we obtain a system of ordinary...
