A note on generic objects and locally finite triangulated categories
Zhe Han
We show that the homotopy category of injective -modules is generically trivial if and only if the derived category of all modules is generically trivial for an algebra . Mor…
Odd graph and its applications to the strong edge coloring
Tao Wang, Xiaodan Zhao
A strong edge coloring of a graph is a proper edge coloring in which every color class is an induced matching. The strong chromatic index of a graph is the minimum nu…
Numerical Methods for the Bogoliubov-Tolmachev-Shirkov model in superconductivity theory
Zhihao Ge, Ruihua Li
In the work, the numerical methods are designed for the Bogoliubov-Tolmachev-Shirkov model in superconductivity theory. The numerical methods are novel and effective to determine t…
Multiphysics Finite Element Methods for a Poroelasticity Model
Xiaobing Feng, Zhihao Ge, Yukun Li
This paper concerns with finite element approximations of a quasi-static poroelasticity model in displacement-pressure formulation which describes the dynamics of poro-elastic mate…
Analysis of a new stabilized discontinuous Galerkin method for the reaction-diffusion problem with discontinuous coefficient
Zhihao Ge, Jiwei Cao
In this paper, a new stabilized discontinuous Galerkin method within a new function space setting is introduced, which involves an extra stabilization term on the normal fluxes acr…
Friedmann's Equations in All Dimensions and Chebyshev's Theorem
Shouxin Chen, Gary W. Gibbons, Yijun Li +1
This short but systematic work demonstrates a link between Chebyshev's theorem and the explicit integration in cosmological time and conformal time of the Friedmann equatio…
