Left invariant nearly pseudo-Kähler structures and the tangent lie group [PDF]

Publ. Math. Debrecen 105 (2024) no. 3-4, 515-522, 2023
Let $G$ be a Lie group, and let $(g,J)$ be a left invariant almost pseudo-Hermitian structure on $G$. It is shown that if $(g,J)$ is also nearly pseudo-K\"{a}hler, then the tangent bundle $TG$ (with its natural Lie group structure induced from $G$) admits a left-invariant nearly pseudo-K\"{a}hler structure.

Embedding almost-complex manifolds in almost-complex euclidean spaces [PDF]

, 2011
We show that any compact almost-complex manifold (M, J) of complex dimension m can be pseudo-holomorphically embedded in R6m equipped with a suitable almost-complex structure

SOME NONLINEAR DIFFERENTIAL INEQUALITIES AND AN APPLICATION TO HÖLDER CONTINUOUS ALMOST COMPLEX STRUCTURES [PDF]

, 2011
. We consider some second order quasilinear partial differential inequalities for real valued functions on the unit ball and find conditions under which there is a lower bound for the supremum of nonnegative solutions that do not vanish at the origin. As

On hypercomplex pseudo-Hermitian manifolds [PDF]

Trends in Complex Analysis, Differential Geometry and Mathematical Physics, World Sci. Publ., Singapore, 2003, 51-62, 2008
The class of the hypercomplex pseudo-Hermitian manifolds is considered. The flatness of the considered manifolds with the 3 parallel complex structures is proved. Conformal transformations of the metrics are introduced. The conformal invariance and the conformal equivalence of the basic types manifolds are studied.

Complex submanifolds of almost complex Euclidean spaces [PDF]

Quart. J. Math. 61 (2010), 401-405, 2009
We prove that a compact Riemann surface can be realized as a pseudo-holomorphic curve of $(\mathbb{R}^4,J)$, for some almost complex structure $J$ if and only if it is an elliptic curve. Furthermore we show that any (almost) complex $2n$-torus can be holomorphically embedded in $(\mathbb{R}^{4n},J)$ for a suitable almost complex structure $J$.

Weakly complex homogeneous spaces [PDF]

, 2012
We complete our recent classification [GMS11] of compact inner symmetric spaces with weakly complex tangent bundle by filling up a case which was left open, and extend this classification to the larger category of compact homogeneous spaces with ...

Invariant Tensors under the Twin Interchange of Norden Metrics on Almost Complex Manifolds [PDF]

Results in Mathematics, 1-18, 30 May 2015, 2015
The object of study are almost complex manifolds with a pair of Norden metrics, mutually associated by means of the almost complex structure. More precisely, a torsion-free connection and tensors with geometric interpretation are found which are invariant under the twin interchange, i.e.

Symplectic cohomologies and deformations

In this note we study the behavior of symplectic cohomology groups under symplectic deformations. Moreover, we show that for compact almost-K\"ahler manifolds $(X,J,g,\omega)$ with $J$ $\mathcal{C}^\infty$-pure and full the space of de Rham harmonic ...
