Aspects of $\kappa$--symmetry

Abstract

We review various aspects of a fermionic gauge symmetry, known as the $\kappa$--symmetry, which plays an important role in formulations of superstrings, supermembranes and higher dimensional extended objects. We also review some aspects of the connection between $\kappa$--symmetric theories and their twistor-like formulations.
