Stability of Complex Foliations Transverse to Fibrations

We prove that a holomorphic foliation of codimension k which is transverse to the fibers of a fibration and has a compact leaf with finite holonomy group is a Seifert fibration, i.e., has all leaves compact with finite holonomy. This is the case for C1-small deformations of a foliation where the original foliation exhibits a compact leaf and the base B of the fibration satisfies H1(B,R) = 0 and...

from linguistics to literature: a linguistic approach to the study of linguistic deviations in the turkish divan of shahriar

chapter i provides an overview of structural linguistics and touches upon the saussurean dichotomies with the final goal of exploring their relevance to the stylistic studies of literature. to provide evidence for the singificance of the study, chapter ii deals with the controversial issue of linguistics and literature, and presents opposing views which, at the same time, have been central to t...

On Complex Surfaces Diffeomorphic to Rational Surfaces

The first major step in proving that every complex surface diffeomorphic to a rational surface is rational was Yau’s theorem [40] that every complex surface of the same homotopy type as P is biholomorphic to P. After this case, however, the problem takes on a different character: there do exist nonrational complex surfaces with the same oriented homotopy type as rational surfaces, and the issue...

The Minimal Number of Singular Fibres of Some Fibrations over Rational Curve

The aim of this paper is to study the minimal number of singular fibres of some fibrations. Given a fibration f : S −→ P, where S is a smooth projective surface of general type, it will be proved that f has at least 5 singular fibres and 5 is the best lower bound. If the Kodaira dimension kod(S) = 1, then all fibration f : S −→ P of genus ≥ 2 has at least 4 singular fibres and 4 is also the bes...
