About Michel Lazard
- Michel Paul Lazard (5 December 1924 – 15 September 1987) was a French mathematician who worked in the theory of Lie groups in the context of p-adic analysis.
- His work took on a life of its own in the hands of Daniel Quillen in the late 20th century.
- Quillen's discovery, that a ring Lazard used to classify formal group laws was isomorphic to an important ring in topology, led to the subject of chromatic homotopy theory. Lazard's self-contained treatise on one-dimensional formal groups also gave rise to the field of p-divisible groups.
- His major contributions are: The classification of p-adic Lie groups: every p-adic Lie group is a closed subgroup of G L n ( Z p ) {\displaystyle {\rm {GL}}_{n}(\mathbb {Z} _{p})} . The classification of (1-dimensional commutative) formal groups. The universal formal group law coefficient ring (Lazard's universal ring) is a polynomial ring. The concept of "analyseurs", reinvented by J.
- Peter May under the name operads.
