Michael Hopkins is a mathematician at Harvard University.
Hopkins is a world leading researcher in algebraic topology and (stable-)homotopy theory.
Among his notable achievements are his work on the Ravenel conjectures, the introduction and discussion of the generalized cohomology theory tmf and its string orientation, a formalization and construction of differential cohomology, the proof of the Kervaire invariant problem. More recently via Jacob Lurie‘s work on the cobordism hypothesis Hopkins participates in work related to the foundations of quantum field theory.

The construction of tmf was originally announced, as joint work with Mark Mahowald and Haynes Miller, in
(There the spectrum was still called “$eo_2$” instead of “$tmf$”.) The details of the definition then appeared in
