Topology

a smooth closed simply connected four-manifold with definite intersection form has a diagonalizable form, ruling out many smooth structures.

In topology, Donaldson's theorem refers to a smooth closed simply connected four-manifold with definite intersection form has a diagonalizable form, ruling out many smooth structures. This meaning comes from Donaldson (1983) in Journal of Differential Geometry.[1]
