G. Peter Scott

Godfrey Peter Scott, known as Peter Scott, (born 1944) is a British mathematician, known for the Scott core theorem.
Scott received his PhD in 1969 from the University of Warwick under Brian Joseph Sanderson. Scott was a professor at the University of Liverpool and later at the University of Michigan.
His research deals with low-dimensional geometric topology, differential geometry, and geometric group theory. He has done research on the geometric topology of 3-dimensional manifolds, 3-dimensional hyperbolic geometry, minimal surface theory, hyperbolic groups, and Kleinian groups with their associated geometry, topology, and group theory.
In 1973 he proved what is now known as the "Scott core theorem" or the "Scott compact core theorem". This states that every 3-manifold formula_1 with finitely generated fundamental group has a compact core formula_2, "i.e.", formula_2 is a compact submanifold such that inclusion induces a homotopy equivalence between formula_2 and formula_1; the submanifold formula_2 is called a "Scott compact core" of the manifold formula_1. He had previously proved that, given a fundamental group formula_8 of a 3-manifold, if formula_8 is finitely generated then formula_8 must be finitely presented.
In 1986 he was awarded the Senior Berwick Prize. in 2012 he was elected a Fellow of the American Mathematical Society.
