A REMARK ON CONFORMAL SU(p, q)-HOLONOMY
نویسنده
چکیده
If the conformal holonomy group Hol(T) of a simply connected space with conformal structure of signature (2p−1, 2q−1) is reduced to U(p, q) then the conformal holonomy is already contained in the special unitary group SU(p, q). We present two different proofs of this statement, one using conformal tractor calculus and an alternative proof using Sparling’s characterisation of Fefferman metrics.

The conformal analog of Calabi-Yau manifolds
This survey intends to introduce the reader to holonomy theory of Cartan connections. Special attention is given to the normal conformal Cartan connection, uniquely defined for a class of conformally equivalent metrics, and to its holonomy group the ’conformal holonomy group’. We explain the relation between conformal holonomy group and existence of Einstein metrics in the conformal class as we...
متن کاملConformal holonomy, symmetric spaces, and skew symmetric torsion
We consider the question: can the isotropy representation of an irreducible pseudoRiemannian symmetric space be realized as a conformal holonomy group? Using recent results of Čap, Gover and Hammerl, we study the representations of SO(2, 1), PSU(2, 1) and PSp(2, 1) as isotropy groups of irreducible symmetric spaces of signature (3, 2), (4, 4) and (6, 8), respectively, describing the geometry in...
متن کاملCONJUGATE SU(r)-CONNECTIONS AND HOLONOMY GROUPS
In this article we show that when the structure group of the reducible principal bundle P is SU(r) and Q ⊂ P is an SO(r)-subbundle of P , the rank of the holonomy group of a connection which is gauge equivalent to its conjugate connection is less than or equal to [ r 2 ] , and use the estimate to show that for all odd prime r, if the holonomy group of the irreducible connection as above is simp...
متن کاملA remark about the Lie algebra of infinitesimal conformal transformations of the Euclidian space
Infinitesimal conformal transformations of IRn are always polynomial and finitely generated when n > 2. Here we prove that the Lie algebra of infinitesimal conformal polynomial transformations over IRn, n ≥ 2, is maximal in the Lie algebra of polynomial vector fields. When n is greater than 2 and p, q are such that p+ q = n, this implies the maximality of an embedding of so(p + 1, q + 1, IR) in...
متن کاملConformal Holonomy of Bi-invariant Metrics
We discuss in this paper the conformal geometry of bi-invariant metrics on compact semisimple Lie groups. For this purpose we develop a conformal Cartan calculus adapted to this problem. In particular, we derive an explicit formula for the holonomy algebra of the normal conformal Cartan connection of a bi-invariant metric. As an example, we apply this calculus to the group SO(4). Its conformal ...
