Free Field Dynamics in the Generalized AdS (Super)Space
Pure gauge representation for general vacuum background fields (Cartan forms)
in the generalized superspace identified with is found. This
allows us to formulate dynamics of free massless fields in the generalized
space-time and to find their (generalized) conformal and higher spin
field transformation laws. Generic solution of the field equations is also
constructed explicitly. The results are obtained with the aid of the star
product realization of ortosymplectic superalgebras.Comment: Some notes added, corrected typo
Higher Spin Gauge Theories in Various Dimensions
Properties of nonlinear higher spin gauge theories of totally symmetric
massless higher spin fields in anti-de Sitter space of any dimension are
discussed with the emphasize on the general aspects of the approach.Comment: LaTeX, 20 pages, Unified version of the talks delivered at

On the Local Frame in Nonlinear Higher-Spin Equations
Properties of the resolution operator in higher-spin
equations, that leads to local current interactions at the cubic order and
minimally nonlocal higher-order corrections, are formulated in terms of the
condition on the class of master fields of higher-spin theory that restricts
both the dependence on the spinor , variables and on the contractions of
indices between the constituent fields in bilinear terms. The Green function in
the sector of zero-forms is found for the case of constituent fields carrying
helicities of opposite signs. It is shown that the local resolution differs from the conventional De Rham resolution by a
non-local shift.Comment: 26 pages; V2: typos corrected, version published in JHE
