можно принять дистанционное участие в семинаре ОТФ ФИАН
 
Докладчик: C. Iazeolla
 
Тема: "From Weyl ordering to normal ordering and the Central On-Mass-Shell Theorem in VasilievБ─≥s higher-spin gravity"
 
Аннотация:
I will show how a whole space of exact solutions of the Vasiliev 4D equations can be obtained as the fully non-linear completions of first-order perturbative solutions in Weyl ordering (WO). An explicit map connecting the classical moduli of such solutions to Fronsdal fields defined in the standard normal ordering (NO) is constructed at linear level, and applied to the cases of massless particle modes and spherically symmetric higher-spin black holes. I will discuss a proposal for imposing asymptotically AdS boundary conditions order by order in perturbation theory, thereby fixing the WO to NO mapping at higher orders.  These results address a number of open issues in the literature on Vasiliev's theory concerning exact solutions, perturbative schemes, admissible classes of functions, choices of gauge and ordering prescriptions.
