چکیده
We prove that the Birkhoff map Ω for KdV constructed on H 0 (T) can be interpolated between H 0 (T) and L20(T). In particular, the symplectic phase space H 1/2 0 (T) can be described in terms of Birkhoff coordinates.

We analyse the role of the Extended Clifford group in classifying the spectra of phase point operators within the framework laid out by Gibbons et al for setting up Wigner distributions on discrete phase spaces based on finite fields. To do so we regard the set of all the discrete phase spaces as a symplectic vector space over the finite field. Auxiliary results include a derivation of the conj...

We construct functorially a class of algebras using the formalism of double derivations. These algebras extend to higher dimensions Crawley-Boevey and Holland's construction of deformed preprojective algebras and encompass symplectic reflection algebras associated to wreath products. We use this construction to show that the quotient field of a symplectic reflection algebra is " rational " , co...

Complex functions χ(m) where m belongs to a Galois field GF (p ℓ), are considered. Fourier transforms , displacements in the GF (p ℓ) × GF (p ℓ) phase space and symplectic Sp(2, GF (p ℓ)) transforms of these functions are studied. It is shown that the formalism inherits many features from the theory of Galois fields. For example, Frobenius transformations are defined which leave fixed all funct...

Since the fundamental work of Gromov [1] pseudoholomorphic curves have become an object of intensive research because they have important applications in symplectic geometry and low dimensional topology. In this paper we study pseudoholomorphic Bishop discs, which are discs with boundaries in a prescribed submanifold. We consider such a study a natural development of the theory of boundary valu...

Let M be a compact Kähler manifold equipped with a Hamiltonian action of a compact Lie group G. In [Invent. Math. 67 (1982), no. 3, 515–538], Guillemin and Sternberg showed that there is a geometrically natural isomorphism between the G-invariant quantum Hilbert space over M and the quantum Hilbert space over the symplectic quotient M/G. This map, though, is not in general unitary, even to lead...
