The arithmetic local Nori fundamental group
M. Romagny, F. Tonini, L. Zhang
In this paper we introduce the local Nori fundamental group scheme of a reduced scheme or algebraic stack over a perfect field . We give particular attention to the case of fiel…
Degree counting for Toda system with simple singularity : one point blow up
Youngae Lee, Chang-shou Lin, Wen Yang +1
In this paper, we study the degree counting formula of the rank two Toda system with simple singular source when and The key ste…
Non-degeneracy of Gauss curvature equation with negative conic singularity
Juncheng Wei, Lei Zhang
We study the Gauss curvature equation with negative singularities. For a local mean field type equation with only one negative index we prove a uniqueness property. For a global eq…
Local Root Numbers and Spectrum of the Local Descents for Orthogonal Groups: p-adic case
Dihua Jiang, Lei Zhang
We investigate the local descents for special orthogonal groups over p-adic local fields of characteristic zero, and obtain an explicit spectral decomposition of the local descents…
Essentially Finite Vector Bundles on Normal Pseudo-proper Algebraic Stacks
Fabio Tonini, Lei Zhang
Let be a normal, connected and projective variety over an algebraically closed field . It is known that a vector bundle on is essentially finite if and only if it is…
-divided sheaves trivialized by dominant maps are essentially finite
Fabio Tonini, Lei Zhang
By a result of Biswas and Dos Santos, on a smooth and projective variety over an algebraically closed field, a vector bundle trivialized by a proper and surjective map is essential…
