A Note on Casoratian Solutions to Two-Dimensional Toda Lattice 总被引:2,自引:0,他引:2
ZHANG Da-Jun WU Hua 《理论物理通讯》2007,47(3):390-392
In this short paper we generalize the conditions that Casoratian entries satisfy for the two-dlmenslonal Toda lattice. Although we finally conclude that our generalization is trivial in some sense for getting new solutions, our discussion is still helpful for the study of Wronskian technique. 相似文献

In this paper, we develop an enhanced intersection cutting-plane algorithm for solving a mixed integer 0–1 bilinear programming formulation of the linear complementarity problem (LCP). The matrixM associated with the LCP is not assumed to possess any special structure, except that the corresponding feasible region is assumed to be bounded. A procedure is described to generate cuts that are deeper versions of the Tuy intersection cuts, based on a relaxation of the usual polar set. The proposed algorithm then attempts to find an LCP solution in the process of generating either a single or a pair of such strengthened intersection cuts. The process of generating these cuts involves a vertexranking scheme that either finds an LCP solution, or else these cuts eliminate the entire feasible region leading to the conclusion that no LCP solution exists. Computational experience on various test problems is provided.This material is based upon work supported by the National Science Foundation under Grant No. DMII-9121419 to the first author and Grant No. DMII-9114489 to the third author. The authors gratefully acknowledge the constructive suggestions of a referee that helped focus the approach and its presentation. 相似文献

Summary A group of 17 β-carbolines was studied in HPLC and TLC systems in order to predict their partition coefficients (log P values).
On account of the basic or acid character of some of these compounds, an ion pairing system gave the best results. Both HPLC
and TLC data were comparable for log P prediction but severe pH conditions required the use of TLC plates. Retention data
are quantitatively related to lipophilicity (expressed as the Hansch constant) and polarity (as the inductive constant) of
the solute molecule. 相似文献

A justification is given for the convergence of quadratures (namely, the right rectangle and midpoint rules) for the numerical solution of a Volterra bilinear equation of the first kind. Numerical results for some benchmark problems are presented. 相似文献

利用包括多体相互作用和具有SO(5)(或SU(5))对称性的对转动对称微扰的超对称模型方法,对A≈190质量区奇A核的超形变转动带进行系统的研究,无论是E2跃迁γ射线能谱,还是动力学转动惯量都得到与实验结果很好定量符合的结果.这表明,超对称方法不仅可以很好地描述超形变带的整体性质,还可以很好地描述超形变带的ΔI=4分岔和全同带等奇异现象. 相似文献

Efficient pairing computation on supersingular Abelian varieties 总被引:2,自引:0,他引:2

We present a general technique for the efficient computation of pairings on Jacobians of supersingular curves. This formulation,
which we call the eta pairing, generalizes results of Duursma and Lee for computing the Tate pairing on supersingular elliptic
curves in characteristic 3. We then show how our general technique leads to a new algorithm which is about twice as fast as
the Duursma–Lee method. These ideas are applied to elliptic and hyperelliptic curves in characteristic 2 with very efficient
results. In particular, the hyperelliptic case is faster than all previously known pairing algorithms.

在相对论平均场理论框架下,利用粒子数守恒方法处理对关联,给出了具体的理论公式和数值细节;并以24Ne为例,用该方法研究了它的基态和低激发态性质. Particle-number conserving method is adopted to treat the pairing correlations in the relativistic mean-field theory. The formalism and numerical techniques are presented. As an example, the ground state properties and low-lying excited states in~(24)Ne are studied. 相似文献
