First order quojections
A quojection is a Fréchet space \(F\) which is the projective limit of a sequence of Banach spaces \(X_ n\) and surjective mappings \(R_ n: X_{n+1}\to X_ n\). A quojection is called twisted if it is not isomorphic to a product of Banach spaces. [For information about quojections see: the authors, Nato ASI Ser., Ser. C 287, 235-254 (1989; Zbl 0711.46008).] It is known that every quojection is a quotient of a countable product of Banach spaces [see \textit{J. Bonet}, \textit{M. Maestre}, the authors and \textit{D. Vogt}, ibid. 287, 355-356 (1989; Zbl 0711.46007)]. The present paper is devoted to investigation of twisted quojections which are quotients of products of Banach spaces by Banach subspaces.
