Current operators in integrable models: a review
نویسندگان
چکیده
We consider the current operators of one dimensional integrable models. These describe flow conserved charges models, and they play a central role in Generalized Hydrodynamics. present key statements about mean currents finite volume thermodynamic limit, we review various proofs exact formulas. also few new results this review. New contributions include computation Heisenberg spin chains using string hypothesis, simplified formulas limit. discuss implications our for asymptotic behaviour dynamical correlation functions.

متن کاملIntegrable operators and the squares of Hankel operators
Abstract Integrable operators arise in random matrix theory, where they describe the asymptotic eigenvalue distribution of large self-adjoint random matrices from the generalized unitary ensembles. This paper gives sufficient conditions for an integrable operator to be the square of a Hankel operator, and applies the condition to the Airy, associated Laguerre, modified Bessel and Whittaker func...

The title refers to a set of three interactive graphics packages produced by Lascaux Graphics, 3771 E. Guthrie Mt Place, Tucson, Arizona AZ 85718, USA. Fields & Operators (F&O) has been advertised in the American Mathematical Monthly for the past year or so, but the other two programs were new to me. Although they address different issues, and can be purchased independently, the three packages ...
متن کاملIntegrable Systems and their Recursion Operators
In this paper we discuss the structure of recursion operators. We show that recursion operators of evolution equations have a nonlocal part that is determined by symmetries and cosymmetries. This enables us to compute recursion operators more systematically. Under certain conditions (which hold for all examples known to us) Nijenhuis operators are well defined, i.e., they give rise to hierarchi...
