Dual Forms of the Squares of Nijenhuis Tensor
Jun Ling
We express the dual forms of squares of Nijenhuis tensor in terms of the second order component derivatives of the exterior derivative on differential forms and give new vanishing…
The Square of Nijenhuis Tensor and Its Vanishing Results
Jun Ling
We give the strong form and the weak form of the square of Nijenhuis tensor, and some vanish results of the square.
A Function obstruction to the Existence of Complex Structures
Jun Ling
We construct a function for almost-complex Riemannian manifolds. Non-vanishing of the function for the almost-complex structure implies the almost-complex structure is not integrab…
The Non-existence of Complex Sphere ()
Jun Ling
There is error in (2.1). I am very sorry for inconvenience.
A Class of Monotonic Quantities along the Ricci Flow
Jun Ling
We construct a class of monotonic quantities along the normalized Ricci flow on closed n-dimensional manifolds.
Some Asymptotic Behavior of the first Eigenvalue along the Ricci Flow
Jun Ling
We study some asymptotic behavior of the first nonzero eigenvalue of the Lalacian along the normalized Ricci flow and give a direct short proof for an asymptotic upper limit estima…
