Locally conformally Kähler solvmanifolds: a survey [PDF]

open access: yesComplex Manifolds, 2019
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 invariant LCK structures on solvmanifolds and present original results ...

A note on compact solvmanifolds with Kahler structures [PDF]

open access: yesOsaka Journal of Mathematics, 2004
In this note we show that a compact solvmanifold admits a Kstructure if and only if it is a finite quotient of a complex torus which has a structure of a com- plex torus bundle over a complex torus.

Pseudo-Riemannian Sasaki solvmanifolds [PDF]

open access: green, 2022
We study a class of left-invariant pseudo-Riemannian Sasaki metrics on solvable Lie groups, which can be characterized by the property that the zero level set of the moment map relative to the action of some one-parameter subgroup $\{\exp tX\}$ is a normal nilpotent subgroup commuting with $\{\exp tX\}$, and $X$ is not lightlike.

The Anosov theorem for exponential solvmanifolds [PDF]

open access: bronzePacific Journal of Mathematics, 1995
The authors exhibit a class \({\mathcal N} {\mathcal R}\) of compact solvmanifolds such that for any \(S \in {\mathcal N} {\mathcal R}\) and any selfmap \(f : S \to S\) the Nielsen number \(N(f)\) equals the absolute value \(|L(f) |\) of the Lefschetz number.

Cohomologically symplectic solvmanifolds are symplectic [PDF]

open access: bronzeJournal of Symplectic Geometry, 2011
We consider aspherical manifolds with torsion-free virtually polycyclic fundamental groups, constructed by Baues. We prove that if those manifolds are cohomologically symplectic then they are symplectic. As a corollary we show that cohomologically symplectic solvmanifolds are symplectic.

Infra-solvmanifolds of dimension four [PDF]

open access: bronzeBulletin of the Australian Mathematical Society, 2000
The article states some results obtained by the author in his thesis: The author considers compact 4-manifolds that are the quotient of some simply connected solvable Lie group \(S\) by an isometric action of a group \(\Gamma\). When \(S\) is solvable it has been shown that the isomorphism class of the fundamental group of such a manifold determines ...

Tessellations of solvmanifolds [PDF]

open access: yesTransactions of the American Mathematical Society, 1998
Let A A be a closed subgroup of a connected, solvable Lie group  G G , such that the homogeneous space A ∖ G A\backslash G is simply connected. As a special case of a theorem of C. T. C. Wall, it is known that every tessellation A ∖ G /

Weyl-Einstein structures on conformal solvmanifolds [PDF]

open access: yesGeometriae Dedicata, 2022
A conformal Lie group is a conformal manifold (M, c) such that M has a Lie group structure and c is the conformal structure defined by a left-invariant metric g on M. We study Weyl-Einstein structures on conformal solvable Lie groups and on their compact

On Some Structural Components of Nilsolitons

open access: yesMathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
In this paper, we study nilpotent Lie algebras that admit nilsoliton metric with simple pre‐Einstein derivation. Given a Lie algebra η, we would like to compute as much of its structure as possible. The structural components we consider in this study are the structure constants, the index, and the rank of the nilsoliton derivations.
