Теорема Банаха-Гротендика для проетивных шкал пространств

The paper is devoted to investigation of duality between projective and inductive scales of spaces. The notion of dual scale is introduced for projectively rigged projective scale of locally convex spaces (LCS). It allows to extend classical Banach and Banach-Grothendieck theorems on coarse reflexivity to the case of projective scales of LCS
