This article is concerned with second-order necessary and sufficient optimality conditions for optimal control problems governed by 3-dimensional Navier-Stokes
Helicity is defined as H=V.ω, where V and ω are the velocity and vorticity vectors, respectively.Many works have pointed out that the larger the helicity is,
A fuzzy bi-matrix game (FBG), namely a two-person non-zero-sum game with fuzzy strategies and fuzzy payoffs is proposed. We have defined and analyzed the optima
