Coefficient Riemann--Hilbert for an Affine Singular Foliation

Qingyun Zeng

For the affine foliation $⟨ x \partial_{x}, y \partial_{x} ⟩$ , we prove that smooth coefficient integration is a strictly unital $A_{\infty}$ quasi-equivalence on every ordinary…

Higher Riemann-Hilbert Correspondence and Descent for Regular Foliations

Qingyun Zeng

Let $F \subset T M$ be a regular foliation. We construct an $A_{\infty}$ integration functor from globally bounded finite-rank leafwise cohesive modules with locally constan…

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…
