Poincaré-invariant generalizations of the Galilei-invariant Calogero-MoserN-particle systems are studied. A quantization of the classical integralsS1, ...,SN is presented such that the operatorsŜ1, ...,ŜN mutually commute. As a corollary it follows thatS1, ...,SN Poisson commute. These results hinge on functional equations satisfied by the Weierstrass σ- and ℘-functions. A generalized Cauchy identity involving the σ-function leads to anN×N matrixL whose symmetric functions are proportional toS1… 
Systems of Calogero-Moser Type
We survey results on Galilei-and Poincare-invariant CalogeroMoser and Toda N-particle systems, both in the context of classical mechanics and of quantum mechanics. Special attention is given to
Zero-Eigenvalue Eigenfunctions for Differences of Elliptic Relativistic Calogero-Moser Hamiltonians
Letting Al(x) denote the commuting analytic difference operators of elliptic relativistic Calogero-Moser type, we present and study zero-eigenvalue eigenfunctions for the operators Al(x) − Al(−y)
Kernel functions and Bäcklund transformations for relativistic Calogero-Moser and Toda systems
We obtain kernel functions associated with the quantum relativistic Toda systems, both for the periodic version and for the nonperiodic version with its dual. This involves taking limits of
Generalized Lamé functions. I. The elliptic case
We present and study a class of functions associated with the two-particle quantum relativistic Calogero–Moser system with elliptic interactions. The functions may be viewed as joint eigenfunctions
Dynamical r-matrices for the Elliptic Calogero-Moser Model
LPTHE-93-42hep-th/9308060Abstract. For the integrable N-particle Calogero-Moser system with ellipticpotential it is shown that the Lax operator found by Krichever possesses a classicalr-matrix
Separation of variables for the A3 elliptic Calogero-Moser system
We consider the classical elliptic Calogero-Moser model. A set of canonical separated variables for this model has been constructed in Kuznetsov et al. However, the generating function of the
Seiberg-Witten curves and double-elliptic integrable systems
A bstractAn old conjecture claims that commuting Hamiltonians of the double-elliptic integrable system are constructed from the theta-functions associated with Riemann surfaces from the
Deformed Quantum Calogero-Moser Problems and Lie Superalgebras
The deformed quantum Calogero-Moser-Sutherland problems related to the root systems of the contragredient Lie superalgebras are introduced. The construction is based on the notion of the generalized
Hilbert-Schmidt Operators vs. Integrable Systems of Elliptic Calogero-Moser Type I. The Eigenfunction Identities
In this series of papers we study Hilbert-Schmidt integral operators acting on the Hilbert spaces associated with elliptic Calogero-Moser type Hamiltonians. As shown in this first part, the integral


Action-angle maps and scattering theory for some finite-dimensional integrable systems
We construct an action-angle transformation for the Calogero-Moser systems with repulsive potentials, and for relativistic generalizations thereof. This map is shown to be closely related to the wave
Quantum completely integrable systems connected with semi-simple Lie algebras
The quantum version of the dynamical systems whose integrability is related to the root systems of semi-simple Lie algebras are considered. It is proved that the operators Ĵk introduced by Calogero

A Course of Modern Analysis
The volume now gives a somewhat exhaustive account of the various ramifications of the subject, which are set out in an attractive manner and should become indispensable, not only as a textbook for advanced students, but as a work of reference to those whose aim is to extend the knowledge of analysis.
