3. The thesis is devoted to a study of geometric properties of r.i. function F-spaces on non-atomic measure spaces and of continuous linear operators, defi ned on these spa- ces. We expound a theory of narrow operators and pre- sent its applications to problems on generalization of the Daugavet property, on ranges of vector measures, and on iso morphic classification of subspaces of the spaces Lp. We generalize the Pitt theorem on compactness of opera- tors; investigate some properties of bases in L1. It is shown that some classical theorems are false for non- locally convex spaces.
