Michael Artin (born 1934) is an American mathematician and a professor at MIT, known for his contributions to algebraic geometry.
Artin was born in Hamburg, Germany, and brought up in Indiana. He is Armenian through his father, mathematician Emil Artin, and Jewish through his mother.
In the early 1960s Artin spent time at the IHÉS in France, contributing to the SGA4 volumes of the Séminaire de géométrie algébrique, on topos theory and étale cohomology. His work on the problem of characterising the representable functors in the category of schemes has led to the Artin approximation theorem, in local algebra. This work also gave rise to the ideas of an algebraic space and algebraic stack, and has proved very influential in moduli theory. Additionally, he has made contributions to the deformation theory of algebraic varieties. He is currently[update] working on noncommutative rings, especially geometric aspects.
In 2002, Artin won the American Mathematical Society's annual Steele Prize for Lifetime Achievement. In 2005, he was awarded the Harvard Centennial Medal.
