What does this research mean for the field?

Under an explicit integral curvature pinching condition, the mean curvature flow of smooth closed submanifolds of small codimension in complex projective spaces either shrinks to a round point in finite time or converges smoothly to a totally geodesic submanifold, yielding a differentiable sphere theorem.

Establish a convergence theorem for mean curvature flow of smooth closed submanifolds in complex projective spaces under an explicit integral curvature pinching condition.
Analyzed smooth closed submanifolds of small codimension immersed in complex projective spaces with initial Lp-norm bounds on the second fundamental form.
Applied evolution equations for geometric quantities, Sobolev inequalities, and Moser iteration to establish uniform curvature estimates preserving the integral condition.
Demonstrated that the mean curvature flow either contracts smoothly to a round point in finite time or converges to a totally geodesic submanifold as time approaches infinity.
Proved a differentiable sphere theorem showing that any satisfying submanifold is diffeomorphic to either a standard sphere or a complex projective space.
