%0 Journal Article %T Necessary Optimality Conditions for a Dead Oil Isotherm Optimal Control Problem %A Moulay Rchid Sidi Ammi %A Delfim F. M. Torres %J Mathematics %D 2006 %I arXiv %R 10.1007/s10957-007-9244-7 %X We study a system of nonlinear partial differential equations resulting from the traditional modelling of oil engineering within the framework of the mechanics of a continuous medium. Recent results on the problem provide existence, uniqueness and regularity of the optimal solution. Here we obtain the first necessary optimality conditions. %U http://arxiv.org/abs/math/0612376v1
