Marc Culler

Marc Edward Culler (born November 22, 1953) is an American mathematician who works in geometric group theory and low-dimensional topology. A native Californian, Culler did his undergraduate work at the University of California at Santa Barbara and his graduate work at Berkeley where he graduated in 1978. He is now at the University of Illinois at Chicago. Culler is the son of Glen Jacob Culler who was an important early innovator in the development of the Internet.

Work

Culler specializes in group theory,[1] low dimensional topology, 3-manifolds, and hyperbolic geometry. Culler frequently collaborates with Peter Shalen and they have co-authored many papers.[2][3] Culler and Shalen did joint work that related properties of representation varieties of hyperbolic 3-manifold groups to decompositions of 3-manifolds. In particular, Culler and Shalen used the Bass–Serre theory, applied to the function field of the SL(2,C)-Character variety of a 3-manifold, to obtain information about incompressible surfaces in the manifold. Based on this work, Shalen, Cameron Gordon, John Luecke, and Culler proved the cyclic surgery theorem.

Another important contribution by Culler came in a 1986 paper with Karen Vogtmann called "Moduli of graphs and automorphisms of free groups".[4] This paper introduced an object that came to be known as Culler–Vogtmann Outer space.

Culler is one of the authors of a 1994 paper called "Plane curves associated to character varieties of 3-manifolds"[5] which introduced the A-polynomial of a knot[6] or, more generally, of a 3-manifold with one torus boundary component.

Culler is an editor of The New York Journal of Mathematics.[7] He was a Sloan Foundation Research Fellow[8] (1986–1988) and a UIC University Scholar[9][10] (2008). In 2014, he became a Fellow of the American Mathematical Society.[11]

gollark: Since your probability of deciding an election by voting is not very high, the expected value of that is very low, and - since people are very hard to convince away from their views - it's even worse for *discussing* politics.
gollark: Regardless of how much you think the results of elections and such matter, I contest that for an individual, at least, politics is not very important.
gollark: So I appear to have been timed out: obviously, this is a clear sign that Cap and WS's views are correct and stand up by themselves.
gollark: Please pay attention.
gollark: As I said, I lost *ironically* with knowledge of what would happen.
