Nontrivial extensions of three-dimensional Poincare algebra, beyond the supersymmetric one, are explicitly constructed. These algebraic structures are the natural three-dimensional generalizations of fractional supersymmetry of order F already considered in one and two dimensions. Representations of these algebras are exhibited, and unitarity is explicitly checked. It is then shown that these extensions generate symmetries which connect fractional spin states or anyons. Finally, a natural… 

Fractional supersymmetry and Fth-roots of representations

A generalization of super-Lie algebras is presented. It is then shown that all known examples of fractional supersymmetry can be understood in this formulation. However, the incorporation of

Field Theoretic Realizations for Cubic Supersymmetry

We consider a four-dimensional space–time symmetry which is a nontrivial extension of the Poincare algebra, different from supersymmetry and not contradicting a priori the well-known no-go theorems.


Non-Abelian fractional supersymmetry algebra in two dimensions is introduced utilizing Uq(sl(2,ℝ)) at roots of unity. Its representations and the matrix elements are obtained. The dual of it is

Fractional supersymmetry and hierarchy of shape invariant potentials

Fractional supersymmetric quantum mechanics is developed from a generalized Weyl-Heisenberg algebra. The Hamiltonian and the supercharges of fractional supersymmetric dynamical systems are built in

Fractional Supersymmetry and F − fold Lie

It is generally held that supersymmetry is the only non-trivial extension of the Poincaré algebra. This point of view is based on the two theorems [1, 2]. However, as usual, if some of the

Some Results on Cubic and Higher Order Extensions of the Poincare Algebra

In these lectures we study some possible higher order (of degree greater than two) extensions of the Poincare algebra. We first give some general properties of Lie superalgebras with some emphasis on

On Supersymmetric Quantum Mechanics

This paper constitutes a review on N = 2 fractional supersym-metric Quantum Mechanics of order k. The presentation is based on the introduction of a generalized Weyl-Heisenberg algebra W k . It is


Cubic extensions of the Poincare algebra can be constructed in consistency with physical assumptions, and provide new insights for the description of phenomena. In this paper we review some recent

Deformations, Contractions and Classification of Lie Algebras of Order 3

Lie algebras of order F (or F −Lie algebras) are possible generalisations of Lie algebras (F = 1) and Lie superalgebras (F = 2). These structures have been used to implement new non-trivial



Group theoretical foundations of fractional supersymmetry

Fractional supersymmetry denotes a generalization of supersymmetry which may be constructed using a single real generalized Grassmann variable, θ=θ,θn=0, for arbitrary integer n=2,3,.... An explicit

Z3 ‐graded algebras and the cubic root of the supersymmetry translations

A generalization of supersymmetry is proposed based on Z3 ‐graded algebras. Introducing the objects whose ternary commutation relations contain the cubic roots of unity, e2πi/3, e4πi/3 and 1, the

Local Fractional Supersymmetry for Alternative Statistics

A group theory justification of one-dimensional fractional supersymmetry is proposed using an analog of a coset space, just like the one introduced in 1-D supersymmetry. This theory is then gauged to

Geometrical Foundations of Fractional Supersymmetry

A deformed q-calculus is developed on the basis of an algebraic structure involving graded brackets. A number operator and left and right shift operators are constructed for this algebra, and the


Supersymmetric (pseudoclassical) mechanics has recently been generalized to fractional supersymmetric mechanics. In such a construction, the action is invariant under fractional supersymmetry

Relativistic field theories in three dimensions

We provide a complete classification of the unitary irreducible representations of the (2+1)‐dimensional Poincare group. We show, in particular, that only two types of ’’spin’’ are available for
