Abstract
We show that various flavors of Witt vectors are functorial with respect to multiplicative polynomial laws of finite degree. We then deduce that the ptypical Witt vectors are functorial in multiplicative polynomial maps of degree at most p−1. This extra functoriality allows us to extend the ptypical Witt vectors functor from commutative rings to Z/2Tambara functors, for odd primes p. We use these Witt vectors for Tambara functors to describe the components of the dihedral fixedpoints of the real topological Hochschild homology spectrum at odd primes.
