In this work, nonlinear diabetes controlled model with and without complications in a population is considered. The dynamic behavior of by including constant control studied investigated. existence all its possible fixed points investigated as well the conditions local stability considered are set. We also find optimal strategy order to reduce number people having over finite period time. A num...

the aim of this work is to investigate the variational discretization and mixed finite element methods for optimal control problem governed by semi linear parabolic equations with integral constraint. the state and co-state are approximated by the lowest order raviart-thomas mixed finite element spaces and the control is not discreted. optimal error estimates in l2 are established for the state...
