Stiefel-Whitney invariants of quadratic forms over local rings

The Milnor ring of a local ring

“…The only restriction for the local rings is, that the residue field has more than 3 elements. Sections 1,2,3 give a survey of [3], though the definitions of [3] are a bit generalized. In section 4, the analogue of Milnor's map s,,, is given, and section 5 covers the example of a field of characteristic 2.…”
