We study the space of deformations of a smooth foliation of the 5-sphere by complex manifolds

In 2002 Meersseman-Verjovsky [2] constructed a smooth, codimension-one, foliation on 5-sphere by complex surfaces with two compact leaves. The aim of this note is to improve their construction in order to give a smooth foliation on 5-sphere…

We construct a smooth codimension-one foliation on the five-sphere in which every leaf is a symplectic four-manifold and such that the symplectic structure varies smoothly. Our construction implies the existence of a complete regular…

The aim of this paper is to show that Lawson's foliation on the 5-sphere admits a smooth leafwise symplectic structure. The main part of the construction is to show that the Fermat type cubic surface admits an end-periodic symplectic…

This paper has been withdrawn by the author, due to an error in Proposition 2.2.

This submission has been withdrawn by the author and superseded by arXiv:0804.0744.

The paper has been withdrawn by the author due an error in the proof of Theorem 3.2.

In this paper, we prove a result related to the deformation of complex submanifolds, modifying a result of Kodaira (Ann. Math, 75(1), 146-162, 1962).

The aim of this paper is to describe complex foliations on Kahler surfaces.

Some unfortunate errors from our paper math/0505591 are corrected.

This paper has been withdrawn by the author due to errors and bad formalization.

The survey is devoted to Toponogov's conjecture, that {\it if a complete simply connected Riemannian manifold with sectional curvature $\le 4$ and injectivity radius $\ge \pi/2$ has extremal diameter $\pi/2$, then it is isometric to CROSS}.…

We correct a mistake regarding almost complex structures on Hilbert schemes of points in surfaces in arXiv:1510.02449. The error does not affect the main results of the paper, and only affects the proofs of invariance of equivariant…

This paper has been withdrawn because the new one gr-qc/0512095 includes all its results (as well as those in gr-qc/0511016) in a clearer way.

The paper has been withdraw by author due to a crucial error in equation 10.

In this article we give corrections and addendum to the article ``Flops and Poisson deformations of symplectic varieties, Publ. Res. Inst. Math. Sci. {\bf 44} (2008) 259 - 314''.

This article has been withdrawn due to a mistake which is explained in version 2.

This paper has been withdrawn by the author due to a mistake in the section 4.

These are lecture notes of a course given in Pisa, SNS, in february 2002. They provide a classification of holomorphic foliations of nongeneral type on compact Kaehler surfaces.

In this note we point out an error in the above paper and refer to some papers where this error is corrected and a more general theorem is proved.
