Abstract
We indicate how to introduce chemical potentials for higher spin charges in
higher spin anti-de Sitter gravity in a manner that manifestly preserves the
original asymptotic W-symmetry. This is done by switching on a non-vanishing
component of the connection along the temporal (thermal) circles. We first
recall the procedure in the pure gravity case (no higher spin) where the only
chemical potentials”\ are the temperature
and the chemical potential associated with the angular momentum. We then
generalize to the higher spin case. We find that there is no tension with the
W(N) or W(infinity) asymptotic algebra, which is obviously unchanged by the
introduction of the chemical potentials. Our argument is non-perturbative.
