The Lorentz Anomaly via Operator Product Expansion

The emergence of a critical dimension is one of the most striking features of string theory. One way to obtain it is by demanding closure of the Lorentz algebra in the light-cone gauge quantisation, as discovered for bosonic strings more than forty years ago. We give a detailed derivation of this classical result based on the operator product expansion on the Lorentzian world-sheet.

Composite dynamical symmetry of M-branes

It is shown that the previously noticed internal dynamical SO(D− 1) symmetry [1] for relativistic M–branes moving in D–dimensional space–time is naturally realized in the (extended by powers of 1 p+

Lorentz algebra and critical dimension for the bosonic membrane

Lectures on string theory

This book provides an introduction to string theory, at present one of the fastest-growing areas in theoretical high-energy physics. It introduces modern techniques and concepts, such as conformal

A Note on Angular Momentum Commutators in Light-Cone Formulation of Open Bosonic String Theory

We recalculate in a systematic and pedagogical way one of the most important results of Bosonic open string theory in the light-cone formulation, namely the [J^{-i},J^{-j}] commutators, which

M-brane dynamical symmetry and quantization

The recently discovered dynamical symmetry for relativistic extended objects is derived from first principles, and analogues commutators are obtained for the corresponding formal quantum expressions
