Self Dual Einstein Orbifolds with Few Symmetries as Quaternion Kähler Quotients

چکیده

We construct a new family of compact orbifolds O(Θ) with a positive self dual Einstein metric and a one-dimensional group of isometries. Together with another family, introduced in [6] and here denoted by O(Ω), these examples classify all 4-dimensional orbifolds that are quaternion Kähler quotients by a torus of real Grassmannians.

Toric Self-dual Einstein Metrics as Quotients

We use the quaternion Kähler reduction technique to study old and new selfdual Einstein metrics of negative scalar curvature with at least a two-dimensional isometry group, and relate the quotient construction to the hyperbolic eigenfunction Ansatz. We focus in particular on the (semi-)quaternion Kähler quotients of (semi-)quaternion Kähler hyperboloids, analysing the completeness and topology,...

Quaternionic Kähler Reductions of Wolf Spaces

The main purpose of the following article is to introduce a Lie theoretical approach to the problem of classifying pseudo quaternionic-Kähler (QK) reductions of the pseudo QK symmetric spaces, otherwise called generalized Wolf spaces. The history of QK geometry starts with the celebrated Berger’s Theorem [Ber55] which classifies all the irreducible holonomy groups for not locally symmetric pseu...

Null Kähler structures, Symmetries and Integrability

I feel honoured to be able to make this small contribution to the celebration of Jerzy Plebański’s 75th birthday. Plebański has presumably regarded his work on complex relativity as a step towards producing general solutions to the Einstein equations on a real Lorentzian manifold. No one in the mid-seventies could expect that his contributions to the field would underlie the relation between tw...

Ricci Flow Unstable Cell Centered at an Einstein Metric on the Twistor Space of Positive Quaternion Kähler Manifolds of Dimension

We construct a 2-parameter family FZ of Riemannian metrics on the twistor space Z of a positive quaternion Kähler manifold M satisfying the following properties : (1) the family FZ contains an Einstein metric gZ and its scalings, (2) the family FZ is closed under the operation of making the convex sums, (3) the Ricci map g 7→ Ric(g) defines a dynamical system on the family FZ, (4) the Ricci flo...

An important example of a multi-dimensional integrable system is the anti-self-dual Einstein equations. By studying the symmetries of these equations, a recursion operator is found and the associated hierarchy constructed. Owing to the properties of the recursion operator one may construct a hierarchy of symmetries and find the algebra generated by them. In addition, the Lax pair for this hiera...
