Quad-curl equations with Navier type boundary conditions are studied in this paper.Stable order reduced formulations equivalent to the model problems are presen
In this paper,we study linearly first and second order in time,uniquely solvable and unconditionally energy stable numerical schemes to approximate the phase fi
We present a general approach to the construction of conservation laws for the dynamics of nonholonomic rel-ativistic systems. Firstly, we give the definition o
For nonsymmetric saddle point problems,Huang et al.in [Numer.Algor.75 (2017),pp.1161-1191] established a generalized variant of the deteriorated positive semi-d
