Definition

A homomorphism from algebraic K-theory groups or motivic cohomology of a variety to an analytic or cohomological target (e.g., Deligne cohomology, real cohomology, or p-adic syntomic cohomology) that produces real, complex, or p-adic invariants; typical examples are the Beilinson regulator, the Borel regulator for number fields, and syntomic regulators.
