A bstract We develop the embedding formalism to describe symmetric traceless tensors in
Anti-de Sitter space. We use this formalism to construct the bulk-to-bulk propagator of …

We explore the space of static solutions of the recently discovered three-dimensional “new
massive gravity”(NMG), allowing for either sign of the Einstein-Hilbert term and a …

A bstract We show that the galileons can be thought of as Wess-Zumino terms for the
spontaneous breaking of space-time symmetries. Wess-Zumino terms are terms which are …

Using ambient space we develop a fully gauge and o (d, 2)-covariant approach to boundary
values of AdS d+ 1 gauge fields. It is applied to the study of (partially) massless fields in the …

A bstract Cubic interactions of massive and partially-massless totally-symmetric higher-spin
fields in any constant-curvature background of dimension greater than three are …

We examine the question of scale versus conformal invariance on maximally symmetric
curved backgrounds and study general two-derivative conformally invariant free theories of …

An alternative interpretation of the conformal transformations of the metric is discussed
according to which the latter can be viewed as a mapping among Riemannian and Weyl …

Free Lagrangians are found both for gauge and non-gauge bosonic conformal fields of any
symmetry type and in any space–time dimension. Conformal gauge fields of various types …

A bstract We develop a manifestly conformal approach to describe linearised (super)
conformal higher-spin gauge theories in arbitrary conformally flat backgrounds in three and …

The pseudo-conformal scenario is an alternative to inflation in which the early universe is
described by an approximate conformal field theory on flat, Minkowski space. Some fields …
