## On the cooperation algebra of the connective Adams summand## A. Baker, B. Richter
The aim of this paper is to gain explicit information about the
multiplicative structure of
ℓ
_{*}ℓ, where ℓ is the
connective Adams summand at an odd prime p. Our approach differs
from Kane's or Lellmann's because our main technical tool is the
MU-based Künneth spectral sequence. We prove that the algebra
structure on ℓ
_{*}ℓ is inherited from the multiplication on
a Koszul resolution of ℓ.
