The Lambda algebra is a differential graded algebra used in computing homotopy groups of spheres. I will look at an interesting algebra endomorphism of Lambda called "theta", which can be used to construct a variant called the cocomplete Lambda algebra, and also to construct a nice spectral sequence for computing the homology of Lambda.
