Abstract

We generalize the Generic Model Theorem for equivariant presheaves of\nstructures; extending the results of Macintyre and Caicedo. We also introduce a\nnew class of generic cohomologies and show how, for some examples, they\nsimplify to non standard cohomologies.\n Key words and phrases: Generic Model Theorem, Equivariant Structures,\nEquivariant Cohomology.\n Primary fields: Model Theory. Equivariant sheaf cohomology.\n
