Brane bound states, deformations and OM

TL;DR

This paper explores how various poly-vector deformations in supergravity theories introduce different brane charges, providing insights into their effects on brane backgrounds and connections to nonrelativistic and OM theories.

Contribution

It systematically analyzes the impact of bi-, tri-, quadri-, and six-vector deformations on brane backgrounds in supergravity, revealing how they generate specific brane charges.

Findings

Bi-vector deformations add F1 string charge.

Quadri-vector deformations add D3-brane charge.

Tri- and six-vector deformations add M2- and M5-brane charges.

Abstract

We investigate behavior of brane backgrounds under poly-vector deformations in Type IIB and D=11 supergravities. We find that the standard bi-vector deformations add dissolved F1 string charge to a Dp-brane background, quadri-vector deformations add D3-brane charge, tri- and six-vector deformations in D=11 add M2- and M5-brane charges respectively. We discuss these results in the context of NRCS and OM theories.
