Multi-instantons and superstring solitons

TL;DR

This paper constructs multi-instanton solutions in higher-dimensional Yang-Mills theories and derives extended superstring solitons from these solutions, advancing understanding of non-perturbative effects in string theory.

Contribution

It introduces explicit multi-instanton solutions in 8 and 7 dimensions and connects them to superstring solitons in heterotic string theory.

Findings

Multi-instanton solutions in 8 and 7 dimensions obtained.

Extended superstring solitons constructed from higher-dimensional instantons.

Provides new explicit solutions linking gauge theory and string theory.

Abstract

Multi-instanton solutions in the eight and seven dimensional Yang-Mills fields theory is obtained. Extended-soliton solutions to the low-energy heterotic-field-theory equations of motion is constructed from this higher-dimensional multi-instantons.
