F eb 1 99 4 Monodromy Map and Classical r - matrices

چکیده
We compute the Poisson bracket relations for the monodromy matrix of the auxiliary linear problem. If the basic Poisson brackets of the model contain derivatives, this computation leads to a peculiar kind of symmetry breaking which accounts for a 'spontaneous quantiza-tion' of the underlying global gauge group. A classification of possible patterns of symmetry breaking is outlined.

In the last years a lot of work has been concentrated on the study of the behaviour at infinity of polynomial maps (see for example [8], [11], [9], [10], [5], among others). This behaviour can be very complicated, therefore the main idea was to find special classes of polynomial maps which have, in some sense, nice properties at infinity. In this paper, we completely determine the complex algeb...

An introduction to inhomogeneous Poisson groups is given. Poisson inhomogeneous O(p, q) are shown to be coboundary, the generalized classical Yang-Baxter equation having only one-dimensional right hand side. Normal forms of the classical r-matrices for the Poincaré group (inhomogeneous O(1, 3)) are calculated.

Our aim is to find a general approach to the theory of classical solutions of the Garnier system in n-variables, Gn, based on the RiemannHilbert problem and on the geometry of the space of isomonodromy deformations. Our approach consists in determining the monodromy data of the corresponding Fuchsian system that guarantee to have a classical solution of the Garnier system Gn. This leads to the ...

This is a review of recent work on the chiral extensions of the WZNW phase space describing both the extensions based on fields with generic monodromy as well as those using Bloch waves with diagonal monodromy. The symplectic form on the extended phase space is inverted in both cases and the chiral WZNW fields are found to satisfy quadratic Poisson bracket relations characterized by monodromy d...
