Pap, Endre Bijective maps which are close to partial isometries. (English) Zbl 0686.47003 Zb. Rad., Prir.-Mat. Fak., Univ. Novom Sadu, Ser. Mat. 18, No. 1, 119-127 (1988). Summary: It is introduced the notion of partial isometry from a set X onto a set Y which are endowed with the families of pseudometrics. It is proved an estimation for the closeness of a partial linear isometry to a bijective map M from a locally convex space onto a sequentially complete Hausdorff locally convex space.
