K27 as a symmetry of closed bosonic strings and branes

TL;DR

This paper demonstrates that the low energy effective action of the closed bosonic string can be derived from the non-linear realisation of a specific algebraic structure involving K27.

Contribution

It introduces a novel algebraic framework using K27 and its vector representation to encode string dynamics, linking algebraic structures to string theory.

Findings

The algebraic structure reproduces the string's effective action.

The approach provides a new perspective on string symmetries.

It bridges algebraic methods with string theory dynamics.

Abstract

We show that the dynamics encoded in the non-linear realisation of the semi-direct product of the very extended algebra K27 with its vector representation contains the low energy effective action of the closed bosonic string.
