On The KMS Condition for the critical Ising model

open access: yes, 1998
Using the KMS condition and exchange algebras we discuss the monodromy and modular properties of two-point KMS states of the critical Ising model.Comment: 8 pages ...

Discrete asymptotic nets and W-congruences in Plucker line geometry

open access: yes, 2000
The asymptotic lattices and their transformations are studied within the line geometry approach. It is shown that the discrete asymptotic nets are represented by isotropic congruences in the Plucker quadric.

Kinetic and Transport Equations for Localized Excitations in Sine-Gordon Model

open access: yes, 1999
We analyze the kinetic behavior of localized excitations - solitons, breathers and phonons - in Sine-Gordon model. Collision integrals for all type of localized excitation collision processes are constructed, and the kinetic equations are derived.

Functional representation of the Ablowitz-Ladik hierarchy. II

open access: yes, 2002
In this paper I continue studies of the functional representation of the Ablowitz-Ladik hierarchy (ALH). Using formal series solutions of the zero-curvature condition I rederive the functional equations for the tau-functions of the ALH and obtain some ...

Irreducible Representations of an Algebra underlying Hidden Symmetries of a class of Quasi Exactly Solvable Systems of Equations

open access: yes, 1996
The set of linear, differential operators preserving the vector space of couples of polynomials of degrees n and n-2 in one real variable leads to an abstract associative graded algebra A(2).

Time-Dependent Symmetries of Variable-Coefficient Evolution Equations and Graded Lie Algebras

open access: yes, 1997
Polynomial-in-time dependent symmetries are analysed for polynomial-in-time dependent evolution equations. Graded Lie algebras, especially Virasoro algebras, are used to construct nonlinear variable-coefficient evolution equations, both in 1+1 dimensions

Localized induction equation and pseudospherical surfaces

open access: yes, 1994
We describe a close connection between the localized induction equation hierarchy of integrable evolution equations on space curves, and surfaces of constant negative Gauss curvature.Comment: 21 pages, AMSTeX file.

On the new approach to variable separation in the time-dependent Schr\"odinger equation with two space dimensions

open access: yes, 1995
We suggest an effective approach to separation of variables in the Schr\"odinger equation with two space variables. Using it we classify inequivalent potentials $V(x_1,x_2)$ such that the corresponding Schr\" odinger equations admit separation of ...
