چکیده

Lax representation in terms of 2 × 2 matrices is constructed for separable multiply–periodic systems splitting on two tori. Hyperelliptic Kleinian functions and their reduction to elliptic functions are used. Introduction. Completely integrable systems with two degree of freedoms and with dynamics splitting on two tori have been largely investigated during the past years as examples of separable multiply-periodic systems. The list of such systems includes the well known in-tegrable cases of the Hénon-Heiles system [1], several integrable cases of quartic potentials [2], the motion of a particle in the Coulomb potential and in external uniform field, the Chaplygin top [3], etc. A Lax representation for these systems can be readily constructed in terms of a direct product of Lax operators [1], one for each splitting tori, as first proposed in ref.[4]. This approach leads for a system of two

Point transformations for the ordinary differential equations of the form y ′′ = P (x, y) + 3 Q(x, y) y ′ + 3 R(x, y) (y ′) 2 + S(x, y) (y ′) 3 are considered. Some classical results are resumed. Solution for the equivalence problem for the equations of general position is described.

The Calogero equation is used to illustrate the following two aspects of the Painlevé analysis of PDEs: (i) the singular expansions of solutions around characteristic hypersurfaces are neither single-valued functions of independent variables nor single-valued functionals of data; (ii) the truncated singular expansions not necessarily lead to the simplest, elementary, Bäcklund autotransformation...

We continue a recently developed systematic approach to the Bousinesq (Bsq) hierarchy and its algebro-geometric solutions. Our formalism includes a recursive construction of Lax pairs and establishes associated Burchnall-Chaundy curves, Baker-Akhiezer functions and Dubrovin-type equations for analogs of Dirichlet and Neumann divisors. The principal aim of this paper is a detailed theta function...

We consider some natural connections which arise between right-flat (p, q) para-conformal structures and integrable systems. We find that such systems may be formulated in Lax form, with a " Lax p-tuple " of linear differential operators, depending a spectral parameter which lives in (q − 1)-dimensional complex projective space. Generally, the differential operators contain partial derivatives ...
