Harmonic Space Construction of the Quaternionic Taub-NUT metric

چکیده
We present details of the harmonic space construction of a quaternionic extension of the four-dimensional Taub-NUT metric. As the main merit of the harmonic space approach, the metric is obtained in an explicit form following a generic set of rules. It exhibits SU(2) × U(1) isometry group and depends on two parameters, TaubNUT ‘mass’ and the cosmological constant. We consider several limiting cases of interest which correspond to special choices of the involved parameters.

Quaternionic Metrics From Harmonic Superspace: Lagrangian Approach and Quotient Construction
Starting from the most general harmonic superspace action of self-interacting Q+ hypermultiplets in the background of N = 2 conformal supergravity, we derive the general action for the bosonic sigma model with a generic 4n dimensional quaternionic-Kähler (QK) manifold as the target space. The action is determined by the analytic harmonic QK potential and supplies an efficient systematic procedu...
متن کاملGeometric construction of new Taub-NUT instantons
In this paper we exhibit a one-parameter family of new Taub-NUT instantons via connecting the two previously known SU(2) Yang–Mills instantons of unit charge on TaubNUT space by a half-line. The endpoint of the half-line will be the reducible Yang–Mills instanton corresponding to the Eguchi–Hanson–Gibbons L2 harmonic 2-form, while at an inner point we recover the Pope–Yuille instanton construct...
متن کاملGeometric construction of new Yang–Mills instantons over Taub-NUT space
In this paper we exhibit a one-parameter family of new Taub-NUT instantons parameterized by a half-line. The endpoint of the half-line will be the reducible Yang–Mills instanton corresponding to the Eguchi–Hanson–Gibbons L2 harmonic 2-form, while at an inner point we recover the Pope–Yuille instanton constructed as a projection of the Levi– Civitá connection onto the positive su(2)+ ⊂ so(4) sub...
متن کاملGeometric interpretation of Schwarzschild instantons
In this note we address the problem of finding Abelian instantons of finite energy on the Euclidean Schwarzschild manifold. This amounts to construct self-dual L2 harmonic 2-forms on the space. Gibbons found a non-topological L2 harmonic form in the Taub-NUT metric, leading to Abelian instantons with continuous energy. We imitate his construction in the case of the Euclidean Schwarzschild manif...

We classify those manifolds mentioned in the title which have nite topological type. Namely we show that any such connected M 4n is isomorphic to a hyperkk ahler quotient of a at quaternionic vector space H d by an abelian group. We also show that a compact connected and simply connected 3-Sasakian manifold of dimension 4n ? 1 whose isometry group has rank n + 1 is isometric to a 3-Sasakian quo...
