Periodic points on nilmanifolds and solvmanifolds [PDF]

open access: yesPacific Journal of Mathematics, 1994
Let \(M\) be a compact manifold and \(f:M \to M\) a self map on \(M\). For any natural number \(n\), the \(n\)-th iterate of \(f\) is the \(n\)-fold composition \(f^ n:M \to M\). The fixed point set of \(f\) is \(\text{fix} (f)=\{x \in M:f(x)=x\}\). We say that \(x \in M\) is a periodic point of \(f\) is \(x\) is a fixed point of some \(f^ n\) and we ...

Classification of compact complex homogeneous manifolds with pseudo-kählerian structures [PDF]

open access: yes, 2010
In this paper, we apply a modification theorem for a compact homogeneous solvmanifold to compact complex homogeneous manifolds with pseudo-kählerian structures.

Supersymmetric scale-separated AdS3 orientifold vacua of type IIB

open access: yesJournal of High Energy Physics
I construct supersymmetric AdS3 vacua of type IIB string theory that exhibit parametric scale separation in the controlled regime. These solutions arise from compactifications on seven-dimensional manifolds equipped with co-closed G 2-structures, in the ...

Kähler Solvmanifolds

open access: yes, 2003
Compact Kähler solvmanifolds are classified up to biholomorphism. A proof of a conjecture Benson and Gordon, that completely solvable compact Kähler solvmanifolds are tori is deduced from this. The main ingredient in the proof is a restriction theorem for polycyclic Kähler groups proved by Nori and the author.

Examples of Compact Lefschetz Solvmanifolds

open access: yesTokyo Journal of Mathematics, 2002
A symplectic manifold \((M^{2m},\omega)\) is called a Lefschetz manifold if the mapping \(\wedge\omega^{m-1}: H^1_{DR}\to H^{2m-1}_{DR}\) on \(M\) is an isomorphism. By a solvmanifold is meant a homogeneous space \(G/\Gamma\) where \(G\) is a simply connected solvable Lie group and \(\Gamma\) is a lattice.

Maximal symmetry and unimodular solvmanifolds [PDF]

open access: yesPacific Journal of Mathematics, 2019
Recently, it was shown that Einstein solvmanifolds have maximal symmetry in the sense that their isometry groups contain the isometry groups of any other left-invariant metric on the given Lie group. Such a solvable Lie group is necessarily non-unimodular.

Homotopy minimal periods for maps of three-dimensional solvmanifolds [PDF]

open access: yes, 2008
A natural number m is called a homotopy minimal period of a map f:X→X if every map g homotopic to f has periodic points of minimal period m. In this paper we give a description for the sets of homotopy minimal periods of maps of all compact solvmanifolds

On the structure of complex solvmanifolds [PDF]

open access: yesJournal of Differential Geometry, 1988
A connected complex space X is called a solvmanifold if there is a connected complex solvable Lie group G which acts holomorphically and transitively on it. The aim of the paper is to study two classes of solvmanifolds: i) X is Kähler, ii) X is separable by analytic hypersurfaces.

Compact solvmanifolds with calibrated and cocalibrated G2-structures [PDF]

open access: yes, 2020
We give a method to obtain new solvable 7-dimensional Lie algebras endowed with closed and coclosed G2-structures starting from 6-dimensional solvable Lie algebras with symplectic half-flat and half-flat SU(3)-structures, respectively.

On the d-invariant of compact solvmanifolds.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1985
Let G be a connected real Lie group and \(\Gamma\) a closed subgroup of G. Then \(\Gamma\) is called a lattice if G/\(\Gamma\) is compact. Every basis of the Lie algebra \({\mathfrak g}\) of G determines a parallelization of G/\(\Gamma\) and hence by the Thom-Pontryagin construction an element [G/\(\Gamma\) ], the stable homotopy of spheres.
