On the existence of stable compact leaves for transversely holomorphic foliations
Holomorphic foliation holonomy stable leaf
2012/4/17
A transversely holomorphic foliation on a compact complex manifold, exhibits a compact stable leaf if and only if the set of compact leaves is not a zero measure subset of the manifold.

This paper gives a geometric topological proof that exotic ho-motopy 3-spheres do not exist.
Non-existence of non-topological solitons in some types of gauge field theories in Minkowski space
Non-existence of non-topological solitons types of gauge field theories Minkowski space

In this paper the conditions, under which non-topological solitons are absent in Yang-Mills theory coupled to a non-linear scalar field in Minkowski space, are obtained. It is also shown that non-topo...

We prove an extension theorem for effective plt pairs (X, S+B) of non-negative Kodaira dimension (KX +S+B) ≥ 0.The main new ingredient is a refinement of the Ohsawa-Takegoshi
