Landweber–Novikov algebra in the 1960s). In the beginning of the 1970s, he proved his
exact functor theorem
In mathematics, the Landweber exact functor theorem, named after Peter Landweber, is a theorem in algebraic topology. It is known that a complex orientation of a homology theory leads to a formal group law. The Landweber exact functor theorem (or ...
