Kadomtsev–Petviashvili Turning Points and CKP Hierarchy
نویسندگان
چکیده
A characterization of the Kadomtsev-Petviashvili hierarchy type C (CKP) in terms KP tau-function is given. Namely, we prove that CKP can be identified with restriction odd times flows on locus turning points second flow. The notion clarified and connected tau function. Algebraic-geometrical solutions particular elliptic are discussed detail. new identity for theta-functions curves holomorphic involution having fixed obtained.

A New Multi-component Ckp Hierarchy * †
We construct a new multi-component CKP hierarchy based on the eigenfunction symmetry reduction. It contains two types of CKP equation with self-consistent sources which Lax representations are presented. Also it admits reductions to k−constrained CKP hierarchy and to a (1+1)-dimensional soliton hierarchy with self-consistent source, which include two types of Kaup-Kuperschmidt equation with sel...
متن کاملAdditional Symmetries and String Equation of the Ckp Hierarchy
Since its introduction in 1980, the Kadomtsev-Petviashvili(KP) hierarchy [1, 2] is one of the most important research topics in the area of classical integrable systems. In particular, the study of its symmetries plays a central role in the development of this theory. In this context, additional symmetries, which correspond to a special kind of symmetries depending explicitly on the independent...
متن کاملPredicting Turning Points
This paper presents a new method for predicting turning points. The paper formally defines a turning point; develops a probit model for estimating the probability of a turning point; and then examines both the in-sample and out-of-sample forecasting performance of the model. The model performs better than some other methods for predicting turning points. *While working on this paper, all three ...

متن کاملTurning Points in Computer Education
This history of computers in education covers two continents. By analysing the experiences of two people a set of turning points in history is identified. These turning points are in the experienced history and so indicate the impact of changes on the citizens of two countries.
