Superconformal symmetry and hyperKaehler manifolds with torsion [PDF]

open access: green, 2001
The geometry arising from Michelson & Strominger's study of N=4B supersymmetric quantum mechanics with superconformal D(2,1;alpha)-symmetry is a hyperKaehler manifold with torsion (HKT) together with a special homothety.

Hyperkähler geometry of rational curves in twistor spaces

open access: yesComplex Manifolds, 2022
We investigate the pseudo-hyperkähler geometry of higher degree rational curves in the twistor space of a hyperkähler 4-manifold.

Stratification of singular hyperkähler quotients

open access: yesComplex Manifolds, 2022
Hyperkähler quotients by non-free actions are typically singular, but are nevertheless partitioned into smooth hyperkähler manifolds. We show that these partitions are topological stratifications, in a strong sense.

On h-Quasi-Hemi-Slant Riemannian Maps

open access: yesAxioms, 2022
In the present article, we indroduce and study h-quasi-hemi-slant (in short, h-qhs) Riemannian maps and almost h-qhs Riemannian maps from almost quaternionic Hermitian manifolds to Riemannian manifolds. We investigate some fundamental results mainly on h-

Non-toric Cones and Chern-Simons Quivers [PDF]

open access: yes, 2017
We obtain an integral formula for the volume of non-toric tri-Sasaki Einstein manifolds arising from nonabelian hyperkahler quotients. The derivation is based on equivariant localization and generalizes existing formulas for Abelian quotients, which lead

Complex Lagrangians in a hyperKähler manifold and the relative Albanese

open access: yesComplex Manifolds, 2020
Let M be the moduli space of complex Lagrangian submanifolds of a hyperKähler manifold X, and let ω̄ : 𝒜̂ → M be the relative Albanese over M. We prove that 𝒜̂ has a natural holomorphic symplectic structure.

Superconformal mechanics of AdS2 D-brane boundstates

open access: yesJournal of High Energy Physics, 2020
We explicitly construct a family of N $$ \mathcal{N} $$ = 4 superconformal mechanics of dyonic particles, generalizing the work of Anninos et al. [1] to an arbitrary number of particles.

7D supersymmetric Yang-Mills on a 3-Sasakian manifold

open access: yesJournal of High Energy Physics, 2018
In this paper we study 7D maximally supersymmetric Yang-Mills on a specific 3-Sasakian manifold that is the total space of an SO(3)-bundle over ℂP 2. The novelty of this example is that the manifold is not a toric Sasaki-Einstein manifold.

Rigid limit for hypermultiplets and five-dimensional gauge theories

open access: yesJournal of High Energy Physics, 2018
We study the rigid limit of a class of hypermultiplet moduli spaces appearing in Calabi-Yau compactifications of type IIB string theory, which is induced by a local limit of the Calabi-Yau.
