Fefferman-Graham construction and higher-spin fields
Maxim Grigoriev (Institut de physique Lebedev, Moscou)

Résumé :
I briefly review the Fefferman-Graham ambient metric construction and discuss its higher-spin extension. The guiding rule is the sp(2) relations satisfied by the generating functions. It is demonstrated that using this approach one can derive higher spin equations over a generic flat background of the HS algebra. This in turn is known to contain the cocycle determining the full nonlinear system.
