The positive mass theorem for ALE manifolds

Mattias Dahl (1997)

Banach Center Publications

Similarity:

We show what extra condition is necessary to be able to use the positive mass argument of Witten [12] on an asymptotically locally euclidean manifold. Specifically we show that the 'generalized positive action conjecture' holds if one assumes that the signature of the manifold has the correct value.

Dirac operators on hypersurfaces

Similarity:

In this paper some relation among the Dirac operator on a Riemannian spin-manifold $N$ , its projection on some embedded hypersurface $M$ and the Dirac operator on $M$ with respect to the induced (called standard) spin structure are given.

Clifford approach to metric manifolds

Chisholm, J. S. R., Farwell, R. S.

Similarity:

[For the entire collection see Zbl 0742.00067.]For the purpose of providing a comprehensive model for the physical world, the authors set up the notion of a Clifford manifold which, as mentioned below, admits the usual tensor structure and at the same time a spin structure. One considers the spin space generated by a Clifford algebra, namely, the vector space spanned by an orthonormal basis ${e_{j} : j = 1, \dots, n}$ satisfying the condition ${e_{i}, e_{j}} \equiv e_{i} e_{j} = e_{j} e_{i} = 2 I η_{i j}$ , where $I$ denotes the unit scalar of the algebra and ( $η_{i j}$ ) the nonsingular...

On the conformal relation between twistors and Killing spinors

Friedrich, Thomas

Similarity:

[For the entire collection see Zbl 0699.00032.] The author considers the conformal relation between twistors and spinors on a Riemannian spin manifold of dimension $n \geq 3$ . A first integral is constructed for a twistor spinor and various geometric properties of the spin manifold are deduced. The notions of a conformal deformation and a Killing spinor are considered and such a deformation of a twistor spinor into a Killing spinor and conditions for the equivalence of these quantities is indicated. ...
