The proposed relations for the coefficient ring of the 2-typization of the universal Abel formal group law
Let be the universal Abel formal group law, and let its -typization have coefficient ring presented as a quotient of the localized Brown–Peterson coefficient ring . Write for the ideal of relations and let . For indices and , let denote a monomial not divisible by any . The proposed relations. The coefficient ring is isomorphic to
and all generating relations have the form
These relations are motivated by explicit low-degree computations of the kernel of the classifying map for the -typized Abel formal group law; the parser supplies no evidence that the proposed presentation has been proved or disproved, so its status remains open.
