Estimates for the rank of A MN V - UA MN and more general displacement of A MN are presented,where A MN is the weighted pseudoinverse of a matrix A.The results are applied to the ...
It is widely believed that quadratic coefficients cannot be estimated from eight data in cubical array. This paper illustrates the estimation of those coefficients by means of by ...
The Lyapunov function method is the focus of this paper in proving marginal stability, asymptotical or globally asymptotical stability of discrete dynamic systems. We show that th...
We develop numerical methods for solving nonlinear equations of conservation laws with flux function that depends on discontinuous coefficients. Using a relaxation approximation, ...
This paper presents a new symbolic algorithm to compute the singular initial value problem of second-order ordinary differential equations using Adomian decomposition method. The ...
