-SDYM fields and heavenly spaces: II. Reductions of the -SDYM system
Reductions of self-dual Yang-Mills (SDYM) system for -bracket Lie
algebra to the Husain-Park (HP) heavenly equation and to
sl(N,{\boldmath{C}) SDYM equation are given. An example of a sequence of
chiral fields () tending for to a curved heavenly
space is found.Comment: 18 page
The Weyl bundle as a differentiable manifold
Construction of an infinite dimensional differentiable manifold not modelled on any Banach space is proposed. Definition, metric
and differential structures of a Weyl algebra and a Weyl algebra bundle are
presented. Continuity of the -product in the Tichonov topology is
proved. Construction of the -product of the Fedosov type in terms of theory
of connection in a fibre bundle is explained.Comment: 31 pages; revised version - some typoes have been eliminated,

-SDYM Fields and Heavenly Spaces. I. -SDYM equations as an integrable system
It is shown that the self-dual Yang-Mills (SDYM) equations for the
-bracket Lie algebra on a heavenly space can be reduced to one equation
(the \it master equation\rm). Two hierarchies of conservation laws for this
equation are constructed. Then the twistor transform and a solution to the
Riemann-Hilbert problem are given.Comment: 25 page
