Collapsing domain walls with $Z_{2}$ -violating coupling to thermalized fermions and their impact on gravitational wave detections

Qing-Quan Zeng, Xi He, Zhao-Huan Yu +1

We study the dynamics of domain walls formed through the spontaneous breaking of an approximate $Z_{2}$ symmetry in a scalar field, focusing on their collapse under the infl…

Derived Lie $\infty$ -groupoids and algebroids in higher differential geometry

Qingyun Zeng

We study various problems arising in higher differential geometry using {\it derived Lie $\infty$ -groupoids and algebroids}.We first study Lie $\infty$ -groupoids in various categor…

Higher Riemann-Hilbert correspondence for foliations

Qingyun Zeng

This paper explores foliated differential graded algebras (dga) and their role in extending fundamental theorems of differential geometry to foliations. We establish an $A_{\infty}…
