Contribution
It introduces the role of discrete deformations in magnetised brane configurations within type-I vacua, building on the foundational work of Fradkin and Tseytlin.
Findings
Discrete B-field deformations affect brane configurations.
Magnetised branes lead to novel vacua structures.
Enhanced understanding of string compactification mechanisms.
Abstract
In a classic paper, Fradkin and Tseytlin showed how magnetic deformations can be introduced in open strings. In this contribution we review some recent work on type-I vacua with magnetised branes and describe the role of additional discrete deformations, related to quantised values of the NS-NS antisymmetric tensor B_ab.
