MPIM Lecture Hall We describe a bar-cobar duality between presheaves and copresheaves on a category of trees, and show that it restricts to such a duality for infinity-operads and infinity-cooperads. For ordinary operads, it specializes to the classical cases studied by Getzler-Jones and Ginzburg-Kapranov. (The lecture is based on joint work with Eric Hoffbeck.)
