Controllability Theory of the GDP of All Member States of The UN

Abstract

The function $p\in L_{\infty}([\sigma,t],P), g \in L_{\infty}([\sigma,t],Q)$ are called the private firms’ control strategy and the governments’ (solidarity) strategy functions or controls respectively. The strategies p and g are used to steer initial value ψ ≡ x ₀ of the nations’ gross domestic to a target x1 in time t1.
