We show in this paper that there exists a deep relationship between the differential topology of S 2-knots in ℝ4 and their symplectic geometry. In particular, we use symplectic tools to define a real-valued topological invariant of a knotted S 2 in ℝ4 (see Section 3.4 below). Here are the main results which motivate this definition.
