Some new results on three-dimensional knots in closed two-connected 6-manifolds. Part 2 (proofs of main theorems)

In the first part of this paper some statements were given, describing the action of the Haefliger group of 3-knots in the 6-sphere on the set of 3-knots in a 2- connected 6-manifold. Here we provide detailed proofs of these statements.
