Helmut Hofer, Professor in the School of Mathematics, joined the Institute Faculty in 2009. One of the founders of the area of symplectic topology, Hofer works on symplectic geometry, dynamical systems, and partial differential equations. His fundamental contributions to the field have led to a new area of mathematics known as Hofer geometry.
Agustin Moreno, Member in the School of Mathematics, is exploring a restricted case of the three-body problem—a concept that considers the complex motion of three masses under the influence of a force such as gravity.
Ed Witten, Charles Simonyi Professor in the School of Natural
Sciences, and Helmut Hofer, Professor in the School of Mathematics,
along with Marc Lackenby, Martin R. Bridson, and Rahul
Pandharipande, have co-authored Lectures on Geometry
Derek and I had several conversations during lunches about the potential for “The Symplectic Piece.” And he continued to attend occasional lectures on the subject, searching for a way to map symplectic geometry onto a musical score.
The mathematical problems arising from modern celestial
mechanics, which originated with Isaac Newton’s Principia
in 1687, have led to many mathematical theories. Poincaré
(1854–1912) discovered that a system of several celestial bodies
