A Priori Bounds for the Vorticity of Axis Symmetric Solutions to the Navier-Stokes Equations

Jennifer Burke, Qi S. Zhang

We obtain a pointwise, a priori bound for the vorticity of axis symmetric solutions to the 3 dimensional Navier-Stokes equations. The bound is in the form of a reciprocal of a powe…

Heat kernel bounds, ancient $κ$ solutions and the Poincaré conjecture

Qi S. Zhang

We establish certain Gaussian type upper bound for the heat kernel of the conjugate heat equation associated with 3 dimensional ancient $κ$ solutions to the Ricci flow. As an appli…

Stationary Solutions of SPDEs and Infinite Horizon BDSDEs with Non-Lipschitz Coefficients

Qi Zhang, Huaizhong Zhao

We prove a general theorem that the $L_{ρ}^{2} (R^{d}; R^{1}) \otimes L_{ρ}^{2} (R^{d}; R^{d})$ valued solution of an infinite horizon backward doubl…

Singular symplectic flops and Ruan cohomology

Bohui Chen, An-Min Li, Qi Zhang +1

In this paper, we study the symplectic geometry of singular conifolds of the finite group quotient $W_{r} = {(x, y, z, t) ∣ x y - z^{2 r} + t^{2} = 0} / μ_{r} (a, - a, 1, 0), r \geq 1,$ which we call or…
