In this paper, we investigate the local exact controllability of an age structured problem modelling the ability of malaria vectors to shift their biting time to avoid the stressful environmental conditions generated by ...

In the present paper, we study energy decay and exact boundary controllability for a system of n one-dimensional linear wave equations coupled in parallel. The control obtained is a square integrable of the Neuman type for ...

In this work we study the asymptotic behavior of the solutions of the linear Klein Gordon equation in R-N, N >= 1. We prove that local energy of solutions to the Cauchy problem decays polynomially. Afterwards, we use the ...

Neste trabalho estudamos o problema de controlabilidade exata na fronteira para um sistema de equações de onda acopladas em paralelo, em domínios suave por partes do plano, sob ação de controle do tipo Neuman. Utilizando ...
