Sign-switch equivalence for Clifford algebras #

Adjoining one positive line identifies the Clifford algebras of a quadratic form and its negation. The construction is generic over a commutative ring.

    The sign-switch equivalence sends a generating pair to the product with the new positive generator plus its scalar component times the new positive generator.

    The inverse sign-switch equivalence has the same equation on Clifford generators.
