  This paper establishes a connection between equivariant ring spectra and Witt
vectors in the sense of Dress and Siebeneicher. Given a commutative
ringspectrum T in the highly structured sense, that is, an
E-infinity-ringspectrum, with action of a finite group G we construct a
ringhomomorphism from the ring of G-typical Witt vectors of the zeroth homotopy
group of T to the zeroth homotopy group of the G-fixed point spectrum of T. In
the particular case, where T is the periodic unitary cobordism spectrum
introduced by Strickland, we show that this ringhomomorphism is injective, and
we interpret this in terms of equivariant cobordism.
