Howard Alan Masur is an American mathematician who works on topology, geometry, and combinatorial group theory. [1] [2]
Masur was an invited speaker at the 1994 International Congress of Mathematicians in Zürich. [3] and is a fellow of the American Mathematical Society. [4]
Along with Yair Minsky, Masur is one of the pioneers of the study of curve complex geometry. [5] He also contributed to the understanding of the convergence of geodesic rays in Teichmüller theory. [6]
Masur was a Ph.D. student of Albert Marden at the University of Minnesota-Minneapolis. [7]
The Hubbard–Masur theorem is named after Masur and John H. Hubbard. [8] In 2009, a conference of mathematicians honored Masur's 60th birthday in France. [9]
John Willard Milnor is an American mathematician known for his work in differential topology, algebraic K-theory and low-dimensional holomorphic dynamical systems. Milnor is a distinguished professor at Stony Brook University and one of the five mathematicians to have won the Fields Medal, the Wolf Prize, and the Abel Prize.
Curtis Tracy McMullen is an American mathematician who is the Cabot Professor of Mathematics at Harvard University. He was awarded the Fields Medal in 1998 for his work in complex dynamics, hyperbolic geometry and Teichmüller theory.
In mathematics, the Teichmüller space of a (real) topological surface , is a space that parametrizes complex structures on up to the action of homeomorphisms that are isotopic to the identity homeomorphism. Teichmüller spaces are named after Oswald Teichmüller.
The Nielsen realization problem is a question asked by Jakob Nielsen about whether finite subgroups of mapping class groups can act on surfaces, that was answered positively by Steven Kerckhoff.
Maryam Mirzakhani was an Iranian mathematician and a professor of mathematics at Stanford University. Her research topics included Teichmüller theory, hyperbolic geometry, ergodic theory, and symplectic geometry. In 2005, as a result of her research, she was honored in Popular Science's fourth annual "Brilliant 10" in which she was acknowledged as one of the top 10 young minds who have pushed their fields in innovative directions.
John Coleman Moore was an American mathematician. The Borel−Moore homology and Eilenberg–Moore spectral sequence are named after him.
The mathematician Shmuel Aaron Weinberger is an American topologist. He completed a PhD in mathematics in 1982 at New York University under the direction of Sylvain Cappell. Weinberger was, from 1994 to 1996, the Thomas A. Scott Professor of Mathematics at the University of Pennsylvania, and he is currently the Andrew MacLeish Professor of Mathematics and chair of the Mathematics department at the University of Chicago.
Karen Vogtmann (born July 13, 1949 in Pittsburg, California) is an American mathematician working primarily in the area of geometric group theory. She is known for having introduced, in a 1986 paper with Marc Culler, an object now known as the Culler–Vogtmann Outer space. The Outer space is a free group analog of the Teichmüller space of a Riemann surface and is particularly useful in the study of the group of outer automorphisms of the free group on n generators, Out(Fn). Vogtmann is a professor of mathematics at Cornell University and the University of Warwick.
Michael Jerome Hopkins is an American mathematician known for work in algebraic topology.
Robert Leamon Bryant is an American mathematician. He works at Duke University and specializes in differential geometry.
Julius L. Shaneson is an American mathematician. He works at the University of Pennsylvania, where he was department chair from 2002 to 2006 and is currently the Class of 1939 Professor of Mathematics.
Anton V. Zorich is a Russian mathematician at the Institut de mathématiques de Jussieu. He is the son of Vladimir A. Zorich. He received his Ph.D. from Moscow State University under the supervision of Sergei Novikov.
Clifford John Earle, Jr. was an American mathematician who specialized in complex variables and Teichmüller spaces.
Yair Nathan Minsky is an Israeli-American mathematician whose research concerns three-dimensional topology, differential geometry, group theory and holomorphic dynamics. He is a professor at Yale University. He is known for having proved Thurston's ending lamination conjecture and as a student of curve complex geometry.
Guoliang Yu is a Chinese American mathematician. After receiving his Ph.D from SUNY at Stony Brook in 1991 under the direction of Ronald G. Douglas, Yu spent time at the Mathematical Sciences Research Institute (1991–1992), the University of Colorado at Boulder (1992–2000), Vanderbilt University (2000–2012), and a variety of visiting positions. He currently holds the Powell Chair in Mathematics and was appointed University Distinguished Professor in 2018 at Texas A&M University. He is a fellow of the American Mathematical Society.
Karsten Grove is a Danish-American mathematician working in metric and differential geometry, differential topology and global analysis, mainly in topics related to global Riemannian geometry, Alexandrov geometry, isometric group actions and manifolds with positive or nonnegative sectional curvature.
Francis Bonahon is a French mathematician, specializing in low-dimensional topology.
Albert Marden is an American mathematician, specializing in complex analysis and hyperbolic geometry.
Mark Sapir was a U.S. and Russian mathematician working in geometric group theory, semigroup theory and combinatorial algebra. He was a Centennial Professor of Mathematics in the Department of Mathematics at Vanderbilt University.
Ronald Alan Fintushel is an American mathematician, specializing in low-dimensional geometric topology and the mathematics of gauge theory.
