Higher-order expansions of powered extremes of normal samples
Wei Zhou, Chengxiu Ling
In this paper, higher-order expansions for distributions and densities of powered extremes of standard normal random sequences are established under an optimal choice of normalized…
Bulk Superconductivity in Fe1+yTe0.6Se0.4 Induced by Removal of Excess Fe
Wei Zhou, Yue Sun, Shuo Zhang +7
Experimental evidences from transport, magnetic, and magneto-optical (MO) image measurements confirmed that arsenic (As) vapor annealing was another effective way to induce bulk su…
On representation and regularity of viscosity solutions to degenerate Isaacs equations and certain nonconvex Hessian equations
Wei Zhou
We study the smoothness of the upper and lower value functions of stochastic differential games in the framework of time-homogeneous (possibly degenerate) diffusion processes in a…
Representation and regularity for the Dirichlet problem for real and complex degenerate Hessian equations
Wei Zhou
We consider the Dirichlet problem for positively homogeneous, degenerate elliptic, concave (or convex) Hessian equations. Under natural and necessary conditions on the geometry of…
A probabilistic approach to interior regularity of fully nonlinear degenerate elliptic equations in smooth domains
Wei Zhou
We consider the value function of a stochastic optimal control of degenerate diffusion processes in a domain . We study the smoothness of the value function, under the assumptio…
Quasiderivative method for derivative estimates of solutions to degenerate elliptic equations
Wei Zhou
We give an example of quasiderivatives constructed by random time change, Girsanov's Theorem and Levy's Theorem. As an application, we investigate the smoothness and estimate the d…
