WebWe construct new invariants of quadratic forms over commutative rings, using ideas from Topology. More precisely, we define a hermitian analog of the Bott class with target algebraic K-theory, based on the classification of Clifford modules.These invariants of quadratic forms go beyond the classical invariants defined via the Clifford algebra.
