WebJan 1, 2001 · Under the natural pairing defined by the metric g, the space of cooriented contact elements of B may be thought of as the unit cotangent bundle ST*B. There is a geodesic fl0w on ST*B (dual, under g, to the usual geodesic flow on STB, cf. paragraph (5) below) defined as follows. Let (b0, V0) with Vo C TboB be a cooriented contact element.
