Geometry of Fermionic Constraints in Superstring Theories

TL;DR

This paper explores the geometric structure of fermionic constraints in superstring theories, focusing on models with supersymmetry in target space and extended worldsheet supersymmetry, offering insights into their underlying geometry.

Contribution

It introduces a geometric framework for fermionic constraints in superstring models with extended supersymmetry, replacing traditional kappa-symmetry with a new approach.

Findings

Develops a geometric description of fermionic constraints

Replaces kappa-symmetry with extended worldsheet supersymmetry

Provides new insights into superstring model invariance

Abstract

Considered are superparticle and superstring models invariant under supersymmetry in a target superspace and local extended worldsheet supersymmetry the latter replacing the fermionic $\kappa$--symmetry of the conventional Green--Schwarz formulations.
