A modification of the Skyrme model has been recently proposed, which admits an exact self-dual sector by introduction six scalar fields assembled in a symmetric, positive, and invertible $3\ifmmode\times\else\texttimes\fi{}3$ matrix $h$. In this paper we study soft manners breaking self-duality that model. The crucial observation is equations impose distinct conditions on three eigenvalues $h$,...

This paper proposes a family of robust counterpart for uncertain linear programs (LP) which is obtained for a general definition of the uncertainty region. The relationship between uncertainty sets using norm bod-ies and their corresponding robust counterparts defined by dual norms is presented. Those properties lead us to characterize primal and dual robust counterparts. The researchers show t...
