Displacement structure of weighted pseudoinverses
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 ...

Notes on the stability of dynamic economic systems
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...
