The notion “intermediate bordism group”, which was introduced by P. J. Eccles to investigate filtrations in stable homotopy group of spheres, is considered. А new notion “cobordism groups of stable-framed immersions” is introduced. The classifying space for the new groups is constructed, ranks of the groups are calculated. Hopf invariants and the Kahn-Priddy homomorphism are generalized for cobordism groups of stable-framed immersions.
Keywords: stable homotopy groups of spheres, immersion.
