LIGHTLIKE HYPERSURFACES OF AN INDEFINITE KAEHLER MANIFOLD
Summary: We study the geometry of real light-like hypersurfaces of an indefinite Kähler manifold \(\bar{M}\). We provide new results on such a real light-like hypersurface \(M\) by using the \(F\)-structure of \(M\) induced by the almost complex structure \(J\) of \(\bar{M}\).

This paper introduces the notion of screen generic lightlike submanifolds (SGLSs) of an indefinite Kaehler statistical manifold equipped with a quarter-symmetric non-metric (QSNM) connection, supported by suitable illustrations.

A counterexample to the Hodge conjecture for Kaehler varieties
Summary: The Hodge conjecture asks whether rational Hodge classes on a smooth projective manifolds are generated by the classes of algebraic subsets, or equivalently by Chern classes of coherent sheaves. On a compact Kaehler manifold, Hodge conjecture is

A splitting theorem for extremal Kaehler metrics
Based on recent work of S. K. Donaldson and T. Mabuchi, we prove that any extremal Kaehler metric in the sense of E. Calabi, defined on the product of polarized compact complex projective manifolds is the product of extremal Kaehler metrics on each ...

PeV-Scale SUSY and Cosmic Strings from F-Term Hybrid Inflation
We consider F-term hybrid inflation (FHI) and SUSY breaking in the context of a B−L extension of the MSSM that largely respects a global U(1)R symmetry.

Complex Osserman Kaehler Manifolds
Let H be a 4 dimensional almost Hermitian manifold which satisfies the Kaehler identity. Then H is complex Osserman if and only if H has constant holomorphic sectional curvature. We also classify in arbitrary dimensions all the complex Osserman Kaehler manifolds which do not have 3 eigenvalues.

TOTALLY UMBILICAL CR-SUBMANIFOLDS OF A KAEHLER MANIFOLD
In the present paper we study totally umbilical CR-submanifolds of a Kaehler manifold. A classification theorem for a $D^\perp$-totally umbilical CR-submanifold is proved. The conditions under which a CR- submanifold becomes a CR-product are obtained, and finally a theorem for a CR-submanifold to be a proper CR-product is also ...
