Controllability of discrete-time control systems on the symplectic group Carlos J. Braga Barros, Luiz A. B. San Martin Let x_{n+1} = exp(A+uB)x_{n} be a discrete-time control system on R^{2n}with A and B matrices in the symplectic Lie algebra sp(n, R). This papergives sufficient conditions for the global controllability of the system. Theseconditions are similar to those of [4]. rp-1998-6.pdf |

On an Iterative Method for the Approximate Solution of an Initial and Boundary-Value Problem for a Generalized Boussinesq Model M. Drina Rojas-Medar, Marko A. Rojas-Medar In this work an iteractive method is proposed for finding the approximate solution of an initial and boundary problem for a nonstationary Generalized Boussinesq model for thermally driven convection. The model allows temperature dependent viscosity and thermal conductivity. We give also the convergence rate bounds for the propost method. rp-1998-5.pdf |
