Minimal Axioms for a Field

This file defines constructors to define a Field structure on a Type, while proving a minimum number of equalities.

Main Definitions

• Field.ofMinimalAxioms: Define a Field structure on a Type by proving a minimal set of axioms

Define a Field structure on a Type by proving a minimal set of axioms. Note that this uses the default definitions for npow, nsmul, zsmul, div and sub. See note [reducible non-instances].
