An Exact Solution of Higher Spin Gauge Theory and Its Cosmological Interpretation
Dr. Ergin Sezgin

      After a brief outline of the simplest four dimensional higher spin gauge theory, I will describe our recent exact solution to it. It is invariant under a deformed higher-spin extension of SO(3,1) and it is the only known solution at present other than the standard AdS_4 solution. I will describe an effective Einstein-scalar field theory which admits our solution. Finally, I will discuss the cosmological interpretation of the solution and compare it with the AdS cosmology of Hertog and Horowitz.
