This paper has two essentially unrelated halves. In the first we prove that a closed symplectic four-manifold admitting a fibration by connected, homologically essential Lagrangian tori with "tame" si...
Surgery Diagrams for Contact 3-Manifolds

In two previous papers, the two first-named authors introduced a notion of contact r-surgery along Legendrian knots in contact 3-manifolds. They also showed how (at least in principle) to convert any ...
THE COHOMOLOGY OF LINE BUNDLES ON NON-PRIMARY HOPF MANIFOLDS
non-primary Hopf manifold cohomology line bundles Douady sequence

The purpose of the present paper is to give an elementary method for the computation of the cohomology groups $H^{q}(X,\Omega^{p}_{X}(L)) ,\ (0\leq q\leq n)$ of an n-dimensional non-primary Hopf manif...
It is well-known that a torsion-free linear connection on a light-like manifold (M,g) compatible with the degenerate metric g exists if and only if Rad(TM) is a Killing distribution. In case of existe...
A Note on Kaehlerian Manifolds

The main purpose of the present paper is to study nearly Kaehlerian manifolds. We give the condition for an almost Hermitian manifold to be nearly Kaehlerian.

In this article a special class of Banach manifolds (called QL-manifolds) and mapping between them (QL-mappings) are introduced and some examples are given.
