This is a semi-pedagogical review of a medium size on the exact determination of and the
role played by the low energy effective prepotential in quantum field theory with (broken) …

This thesis presents several new insights on the interface between mathematics and
theoretical physics, with a central role for Riemann surfaces. First of all, the duality between …

We study the mediation of supersymmetry breaking triggered by background fluxes in Type II
string compactifications with Script N= 1 supersymmetry. The mediation arises due to an U …

We demonstrate that, in an appropriate limit, the off-shell M5-brane worldvolume action
effectively captures the scalar potential of Seiberg–Witten theory perturbed by a small …

We study supersymmetry breaking in metastable vacua on the Coulomb branch of
perturbed\(\mathcal {N}= 2\) gauge theories, with gauge group SU (2) and different matter …

A bstract It has been shown that four dimensional\(\mathcal {N}= 2\) gauge theories, softly
broken to\(\mathcal {N}= 1\) by a superpotential term, can accommodate metastable non …

We study the SUSY/non-SUSY duality proposed by Aganagic et al. from Type IIA string and
M-theory perspectives. We find that our brane configuration generalizes the so-called …

抄録 行列模型と言うと, 多体問題に造詣の深い読者は ML Mehta による有名な本 “Random
Matrices” で取り扱われている原子核のレベル間隔の問題を, あるいは中年以上の弦理論研究者は …
