TL;DR
This paper presents a method for stabilizing runaway behaviors in string compactifications by using flux superpotentials, leveraging geometric engineering of quiver gauge theories and homological mirror symmetry.
Contribution
It introduces a novel approach to stabilize fractional branes at del Pezzo singularities in compact models through flux superpotentials, based on geometric engineering and mirror symmetry.
Findings

Flux superpotentials effectively stabilize quiver gauge theories.
Homological mirror symmetry is used to support the construction.
Abstract
We propose a scenario for dynamical supersymmetry breaking in string compactifications based on geometric engineering of quiver gauge theories. In particular we show that the runaway behavior of fractional branes at del Pezzo singularities can be stabilized by a flux superpotential in compact models. Our construction relies on homological mirror symmetry for orientifolds.
