In 1981, Cohen constructed an infinite family of homotopy elements ζk∈ π*(S) represented by h0bk ∈ ExtA3,2(p-1)(pk+1+1)(z/p,Z/p) in the Adams spectral sequence, where p 〉 2 and k ≥ 1. In this paper, w...

Let (Ω* (M), d) be the de Rham cochain complex for a smooth compact closed manifolds M of dimension n. For an odd-degree closed form H, there is a twisted de Rham cochain complex (Ω* (M), d + H∧) and its...

In this paper, a new family of homotopy elements in the stable homotopy groups of spheres represented by h1hnhm γ?s in the Adams spectral sequence is detected, where n-2≥m≥5 and 3≤s 〈p.
