The aim of this paper is to continue the study of Kodaira dimension for almost complex
manifolds, focusing on the case of compact 4-dimensional solvmanifolds without any …

Locally conformal symplectic nilmanifolds with no locally conformal Kähler metrics

G Bazzoni, JC Marrero - Complex Manifolds, 2017 - degruyter.com
We report on a question, posed by L. Ornea and M. Verbitsky in [32], about examples of
compact locally conformal symplectic manifolds without locally conformal Kähler metrics. We …

Locally conformally Kähler structures on four-dimensional solvable Lie algebras

D Angella, M Origlia - Complex Manifolds, 2020 - degruyter.com
We classify and investigate locally conformally Kähler structures on four-dimensional
solvable Lie algebras up to linear equivalence. As an application we can produce many …

Second Chern-Einstein metrics on four-dimensional almost-Hermitian manifolds

G Barbaro, M Lejmi - Complex Manifolds, 2023 - degruyter.com
We study four-dimensional second Chern-Einstein almost-Hermitian manifolds. In the
compact case, we observe that under a certain hypothesis, the Riemannian dual of the Lee …

Second-Chern-Einstein metrics on 4-dimensional almost-Hermitian manifolds

G Barbaro, M Lejmi - arxiv preprint arxiv:2205.03452, 2022 - arxiv.org
We study 4-dimensional second-Chern-Einstein almost-Hermitian manifolds. In the compact
case, we observe that under a certain hypothesis the Riemannian dual of the Lee form is a …

J-Trajectories in 4-Dimensional Solvable Lie Group

Z Erjavec, J Inoguchi - Journal of Nonlinear Science, 2023 - Springer
J-trajectories are arc-length-parameterized curves in almost Hermitian manifolds, which
satisfy the equation∇ γ˙ γ˙= q J γ˙. In this paper, J-trajectories in the solvable Lie group Sol 1 …

Conformally symplectic structures and the Lefschetz condition

M Lejmi, SO Wilson - arxiv preprint arxiv:2403.12304, 2024 - arxiv.org
This short note provides a symplectic analogue of Vaisman's theorem in complex geometry.
Namely, for any compact symplectic manifold satisfying the hard Lefschetz condition in …

Locally conformally Kähler solvmanifolds: a survey

A Andrada, M Origlia - Complex Manifolds, 2019 - degruyter.com
A Hermitian structure on a manifold is called locally conformally Kähler (LCK) if it locally
admits a conformal change which is Kähler. In this survey we review recent results of …

On the projection of exact Lagrangians in locally conformally symplectic geometry

A Currier - arxiv preprint arxiv:2408.07760, 2024 - arxiv.org
In this paper, we construct examples of exact Lagrangians (of" locally conformally
symplectic" type) in cotangent bundles of closed manifolds with locally conformally …
