Maximally supersymmetric theories do not allow off-shell superspace formulations with
traditional superfields containing a finite set of auxiliary fields. It has become clear that off …

We construct gauge theory of interacting symmetric traceless tensors of all ranks s= 0, 1, 2,
3,… which generalizes Weyl-invariant dilaton gravity to the higher spin case, in any …

We characterize the integral cohomology and the rational homotopy type of the maximal
Borel-equivariantization of the combined Hopf/twistor fibration, and find that subtle relations …

This volume covers the most up-to-date findings on string field theory. It is presented in a
new approach as a result of insights gained from the theory. This includes the use of a …

Realization of the conformal higher spin symmetry on the 4D massless field supermultiplets
is given. The self-conjugated supermultiplets, including the linearized N= 4 super Yang-Mills …

A bstract We derive manifestly covariant actions of spinning particles starting from coadjoint
orbits of isometry groups, by using Hamiltonian reductions. We show that the defining …

An explicit algebraic description of finite Lorentz transformations of vectors in ten‐
dimensional Minkowski space is given by means of a parametrization in terms of the …

We consider algebraic varieties canonically associated with any Lie superalgebra, and
study them in detail for super-Poincaré algebras of physical interest. They are the locus of …

After adding a scalar chiral boson to the usual superspace variables, the four-dimensional
Green-Schwarz superstring is quantized in a manifestly SO (3, 1) super-Poincaré covariant …

After adding seven auxiliary scalar fields, the action for ten-dimensional super-Yang-Mills
contains an equal number of bosonic and fermionic non-gauge fields. Besides being …
