A priori estimates for Donaldson's equation over compact Hermitian manifolds [PDF]

open access: yes, 2013
In this paper we prove a priori estimates for Donaldson's equation $\omega\wedge(\chi+\sqrt{-1}\partial\bar{\partial}\varphi)^{n-1}=e^{F}(\chi+\sqrt{-1}\partial\bar{\partial}\varphi)^{n}$ over a compact Hermitian manifold X of complex dimension n, where $

Natural Diagonal Riemannian Almost Product and Para-Hermitian Cotangent Bundles [PDF]

open access: yes, 2009
We obtain the natural diagonal almost product and locally product structures on the total space of the cotangent bundle of a Riemannian manifold. We find the Riemannian almost product (locally product) and the (almost) para-Hermitian cotangent bundles of

Locally conformal symplectic nilmanifolds with no locally conformal K\"ahler metrics [PDF]

open access: yes, 2014
We obtain an example of a compact locally conformal symplectic nilmanifold which admits no locally conformal K\"ahler metrics. This gives a new positive answer to a question raised by L. Ornea and M. Verbitsky.Comment: 7 pages, no figures.

The weighted Laplacians on real and complex metric measure spaces

open access: yes, 2014
In this short note we compare the weighted Laplacians on real and complex (K\"ahler) metric measure spaces. In the compact case K\"ahler metric measure spaces are considered on Fano manifolds for the study of K\"ahler-Einstein metrics while real metric ...

A neutral relation between metallic structure and almost quadratic {\phi}-structure

open access: yes, 2018
In this paper, metallic structure and almost quadratic metric phi-structure are studied. Based on metallic (polynomial) Riemannian manifold, Kenmotsu quadratic metric manifold, cosymplectic quadratic metric manifold are defined and gave some examples ...

Kahler geometry of toric varieties and extremal metrics

open access: yes, 1997
Recently Guillemin gave an explicit combinatorial way of constructing "toric" Kahler metrics on (symplectic) toric varieties, using only data on the moment polytope. In this paper, differential geometric properties of these metrics are investigated using

Tamed symplectic structures on compact solvmanifolds of completely solvable type [PDF]

open access: yes, 2015
A compact solvmanifold of completely solvable type, i.e. a compact quotient of a completely solvable Lie group by a lattice, has a K\"ahler structure if and only if it is a complex torus.

The Geometry Of Hemi-Slant Submanifolds of a Locally Product Riemannian Manifold

open access: yes, 2014
In the present paper, we study hemi-slant submanifolds of a locally product Riemannian manifold. We prove that the anti-invariant distribution which is involved in the definition of hemi-slant submanifold is integrable and give some applications of this ...

Warped product skew semi-invariant submanifolds of order 1 of a locally product Riemannian manifold

open access: yes, 2014
We introduce warped product skew semi-invariant submanifolds of order $1$ of a locally product Riemannian manifold. We give a necessary and sufficient condition for skew semi-invariant submanifold of order 1 to be a locally warped product.
