Let G be a group, A a G-module, and H a subgroup of G. The standard Ε½ . Ε½ . cohomological transfer map from H \* H, A to H \* G, A is defined in the case that H is of finite index in G and is given explicitly in each dimension by a formula involving a sum over a set of representives for H \_ G.

## Abstract Let __R__ be a Gorenstein ring of finite Krull dimension and __t__ ∈ __R__ a regular element. We show that if the quotient map __R__ β†’ __R/Rt__ has a flat splitting then the transfer morphism of coherent Witt groups Tr~(__R/Rt__)/__R__~ : $ \widetilde W^{i} $(__R/Rt__) β†’ $ \widetilde W^
