Helmut Hofer

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.

The Symplectic Piece

Helmut Hofer and Derek Bermel

The Institute Letter Summer 2012

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.

Celestial Mechanics and a Geometry Based on Area

Helmut Hofer

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 moving under...
