How to Find H-Monopoles in Brane Dynamics

TL;DR

This paper demonstrates that brane dynamics can produce all H-monopoles predicted by S-duality in N=4 superstring compactifications, using duality arguments and 5-brane descriptions.

Contribution

It provides two independent proofs linking brane dynamics to H-monopoles, enhancing understanding of dualities in superstring theory.

Findings

Brane dynamics reproduces all predicted H-monopoles.

Duality methods confirm the existence of H-monopoles.

The 5-brane description offers a complementary perspective.

Abstract

We prove in two different ways that brane dynamics gives rise to all H-monopoles predicted by S-duality of N=4, 4-dimensional superstring compactifications. One method uses heterotic-type II duality and the self-dual 3-brane dynamics, the other uses the 5-brane description of small instantons in SO(32) superstrings.
