**Abstract:**

The theory of integrable partial differential equations (PDEs) has classical
origins in the 19th c., and several examples already appear in the book
of Ince. However its modern inception and the realization of the close
analogy with Hamiltonian mechanics dates to the 1960's. Starting with
the KdV equation of fluid mechanics, there was a sequence of discoveries
of PDEs which possess infinitely many (and often non-obvious) symmetries,
and for which there exist methods of quadrature for all solutions. These
discoveries have been very influential over the past three decades,
and have been shown to be connected to a broad range of other subjects
in mathematics.

Completely integrable systems are special, nonetheless, so the developments
over the past decade of perturbation methods akin to KAM theory for
Hamiltonian systems with infinitely many degrees of freedom, in particular
PDE, are very natural. This workshop will provide a cross-section of
the fields of Hamiltonian PDE, including:

(1) modern developments in techniques of integrability, both algebraic
and more analytically based,

(2) refined asymptotics of integrable systems in the small dispersion
limit or other singular limits,

(3) extension of techniques of quadrature, including elements of inverse
spectral theory and random matrix theory,

(4) KAM theory for PDE and other Hamiltonian systems possessing infinitly
many degrees of freedom, and

(5) Nekhoroshev stability theory and Arnold diffusion in infinite
dimensional systems.
