S(1)XS(2) AS A BAG MEMBRANE AND ITS EINSTEIN-WEYL GEOMETRY

In the hybrid skyrmion in which an anti-de-Sitter bag is imbedded into the skyrmion configuration a S1 x S2 membrane is lying on the compact ified spatial infinity of the bag. The connection between the quark de grees of freedom and the mesonic ones is made through the membrane. Th is 3-dimensional manifold is at the same time a Weyl-Einstein space. W e present what is known until the present time to people working on th e differential geometry of these spaces.
