Pluriclosed and Strominger Kähler–like metrics compatible with abelian complex structures

open access: yesBulletin of the London Mathematical Society, Volume 54, Issue 5, Page 1862-1872, October 2022., 2022
Abstract We show that the existence of a left‐invariant pluriclosed Hermitian metric on a unimodular Lie group with a left‐invariant abelian complex structure forces the group to be 2‐step nilpotent. Moreover, we prove that the pluriclosed flow starting from a left‐invariant Hermitian metric on a 2‐step nilpotent Lie group preserves the Strominger ...

Coincidence Wecken Property for Nilmanifolds [PDF]

open access: yesActa Mathematica Sinica, English Series, 2018
Let $f,g:X\to Y$ be maps from a compact infra-nilmanifold $X$ to a compact nilmanifold $Y$ with $\dim X\ge \dim Y$. In this note, we show that a certain Wecken type property holds, i.e., if the Nielsen number $N(f,g)$ vanishes then $f$ and $g$ are deformable to be coincidence free.

Duality of Hodge numbers of compact complex nilmanifolds

open access: yesComplex Manifolds, 2015
A compact K¨ahlerian manifoldM of dimension n satisfies hp,q(M) = hq,p(M) for each p, q.However, a compact complex manifold does not satisfy the equations in general. In this paper, we consider duality of Hodge numbers of compact complex nilmanifolds.

Black holes and nilmanifolds: quasinormal modes as the fingerprints of extra dimensions?

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We investigate whether quasinormal modes (QNMs) can be used in the search for signatures of extra dimensions. To address a gap in the Beyond the Standard Model (BSM) literature, we focus here on higher dimensions characterised by negative Ricci curvature.

Special holonomy manifolds, domain walls, intersecting branes and T-folds

open access: yesJournal of High Energy Physics, 2020
We discuss the special holonomy metrics of Gibbons, Lu, Pope and Stelle, which were constructed as nilmanifold bundles over a line by uplifting supersymmetric domain wall solutions of supergravity to 11 dimensions.

On the Spectra of Compact Nilmanifolds [PDF]

open access: yesTransactions of the American Mathematical Society, 1985
We show the equivalence of the Howe-Richardson multiplicity formula for compact nilmanifolds and the formula obtained by Corwin and Greenleaf using the Selberg trace formula.

Locally conformal symplectic nilmanifolds with no locally conformal Kähler metrics

open access: yesComplex Manifolds, 2017
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.

Remarks on Hodge numbers and invariant complex structures of compact nilmanifolds

open access: yesComplex Manifolds, 2016
If N is a simply connected real nilpotent Lie group with a Γ-rational complex structure, where Γ is a lattice in N, then for each s, t.We study relations between invariant complex structures and Hodge numbers of compact nilmanifolds from a ...
