Some new results on three-dimensional knots in closed two-connected 6-manifolds. Part 1 (preliminary information and statements of main theorems)

The sets of diffeomorphism classes of 3-knots (framed and non-framed) in manifolds of the form S3 Ч S3#...#S3 Ч S3 are being studied; in particular, the action of Haefliger groups of 3-knots in S6 on these sets is investigated. The results of this paper extend and supplement some earlier results of the author.
