Abstract
We investigate various aspects of higher-spin anti-de Sitter supergravity in
three dimensions as described by Chern-Simons theory based on the
finite-dimensional superalgebra sl(N |N - 1), with the particular case of N = 3
as our prime example. This class of theories serves as a natural
supersymmetrization of the higher-spin gravity theory based on sl(N)
Chern-Simons theories. We demonstrate explicitly that the asymptotic symmetry
algebra contains the N = 2 superconformal algebra in each sector. The
appropriate Killing spinor equations are derived and used to classify existing
and new classical solutions. We also discuss holonomy conditions, higher-spin
black holes and conical defect spacetimes in this class of theories.
