This page is about characterizing the Lazard ring in formal group laws. For the characterization of flat modules see instead at Lazard's criterion.
symmetric monoidal (∞,1)-category of spectra
algebraic topology – application of higher algebra and higher category theory to the study of (stable) homotopy theory
A proof is spelled out in (Kochman 96, theorem 4.4.9). Another proof is indicated in (Hopkins 99, section 2), worked out in (Mathew 12, Wilson 13). Also (Lurie 10, lecture 2, theorem 4) and (Lurie 10, lecture 3).
The proof is originally due to :
Michel Lazard, Sur les groupes de Lie Formels à un Paramètre, Bull. Soc. France 83 (1955) [numdam:BSMF_1955__83__251_0]
A. Fröhlich, Formal group, Lecture Notes in Mathematics 74, Springer (1968)
