%0 Journal Article %T An Immediate Derivation of Maximum Principle in Banach spaces, Assuming Reflexive Input and State Spaces %A d'Alessandro %A Paolo %J Cubo (Temuco) %D 2012 %I Scientific Electronic Library Online %R 10.4067/S0719-06462012000200005 %X we consider a standard setting for the norm optimal problem in banach spaces and show that with a simple argument which invokes some appropriately selected powerful general theorems for banach spaces a straightforward derivation of the maximum principle is obtained. %K linear control systems in banach spaces %K norm optimal control %K support of closed convex sets. %U http://www.scielo.cl/scielo.php?script=sci_abstract&pid=S0719-06462012000200005&lng=en&nrm=iso&tlng=en
