Abstract: In 3-dimensional contact topology, convex surface theory, developed by Giroux, plays a prominent role. In this talk, I will describe a ‘parallel’ story in higher dimensions. In particular I will introduce the notion of overtwisted orange and bypass as technical tools. This is based on joint work with K. Honda.
