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…
Series solutions to the cauchy problem for partial differential equations
Tao Zhang, Alatancang Chen
The method of separation of variables can be used to solve many separable linear partial differential equations (LPDEs). Moreover, variable separation solutions usually are some tr…
Some basic properties of block operator matrices
Guohai Jin, Alatancang Chen
General approach to the multiplication or adjoint operation of block operator matrices with unbounded entries are founded. Furthermore, criteria for self-adjointness of…
On invertible nonnegative Hamiltonian operator matrices
Guohai Jin, Guolin Hou, Alatancang Chen +1
Some new characterizations of nonnegative Hamiltonian operator matrices are given. Several necessary and sufficient conditions for an unbounded nonnegative Hamiltonian operators to…
On symplectic self-adjointness of Hamiltonian operator matrices
Alatancang Chen, Guohai Jin, Deyu Wu
Symplectic self-adjointness of Hamiltonian operator matrices is studied, which arises in symplectic elasticity and optimal control. For the cases of diagonal domain and off-diagona…
