Title: Peg problems and symplectic geometry.

Abstract: The unsolved Toeplitz Square Peg Problem was posed in 1911.  It asks whether all Jordan curves (subsets of the real plane homeomorphic to a circle) contain four points at the vertices of a square. We shall discuss this problem and related "peg" problems.  They sometimes admit a description in terms of symplectic geometry.
No prior knowledge of pegs or of symplectic geometry assumed.  (Joint work with Josh Greene).
