%0 Journal Article %T Evolutionary stable strategies and well posedness property %A L. Pusillo %J Applied Mathematical Sciences %D 2013 %I %X In this paper evolutionary stable strategies, as defined by MaynardSmith, are studied and some existence theorems are given. Approximateevolutionary stable strategies are introduced and a new concept of wellposedness is applied to some problems with only one evolutionary stableequilibrium. %K non cooperative games %K evolutionary stable strategies %K approximate equilibria %K well-posedness %U http://www.m-hikari.com/ams/ams-2013/ams-5-8-2013/pusilloAMS5-8-2013.pdf
