A 3-dimensional model dual to the Rozansky-Witten topological sigma-model with a hyper-Kähler target space is considered. It is demonstrated that a Feynman diagram calculation of the classical part of its partition function yields the Milnor linking number.

The manifest expression for a (Virasoro-like) infinite-dimensional generalization of the 3 + 1-dimensional conformal algebra so(4, 2) is presented in this letter. It provides the arena for integrable models of Anti-de Sitter and conformal gauge theories of higher-generalized-spin fields in realistic dimensions.

We suggest simple models which produce the suitable fermion mass hierarchies and flavor mixing angles based on the supersymmetric SO(10) grand unified theory in 6 dimensions compactified on a T 2 /Z 2 orbifold. The gauge and Higgs fields propagate in 6 dimensions while ordinal chiral matter fields are localized in 4 dimensions. We introduce extra vector-like heavy fields in the extra dimensions...
