Along with Anders Lindstedt, this person is the namesake of a method to approximate periodic solutions to certain differential equations. This mathematician is the namesake of first recurrence maps used to trace paths in chaos theory, and he developed a disk model of hyperbolic geometry. This mathematician conjectured what became a specific case of Thurston's geometrization conjecture: that the three-sphere is the only type of bounded three-dimensional space that contains no holes. Name this mathematician whose conjecture was proven by Grigori  Perelman and was one of the Millennium Prize Problems.
