Upper semi-Weyl and upper semi-Browder spectra of unbounded upper triangular operator matrices
Wurichaihu Bai, Qingmei Bai, Alatancang Chen
In this paper, we study the unbounded upper triangular operator matrix with diagonal domain. Some sufficient and necessary conditions are given under which upper semi-Weyl spectrum…

The invertibility of 2X2 operator matrices
Junjie Huang, Junfeng Sun, Alatancang Chen +1
In this paper the properties of right invertible row operators, i.e., of 1X2 surjective operator matrices are studied. This investigation is based on a specific space decomposition…

Solving some Navier-Stokes Equations with the initial conditions being some complex-valued periodic functions on
Tao Zhang, Alatancang Chen, Fan Bai
In this paper, we utilize some series and an iterative method to solve some Navier-Stokes equations with the initial conditions being some complex-valued periodic functions on $R^3…
