Spin(7)-manifolds and symmetric Yang--Mills instantons
Gabor Etesi
In this Letter we establish a relationship between symmetric SU(2) Yang--Mills instantons and metrics with Spin(7)-holonomy. Our method is based on a slight extension of that of Br…
Geometric construction of new Yang-Mills instantons over Taub-NUT space
Gabor Etesi, Tamas Hausel
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 co…
Non-Turing computations via Malament-Hogarth space-times
Gabor Etesi, Istvan Nemeti
We investigate the Church-Kalmár-Kreisel-Turing Theses concerning theoretical (necessary) limitations of future computers and of deductive sciences, in view of recent results of cl…
A rigidity theorem for nonvacuum initial data
Gabor Etesi
In this note we prove a theorem on non-vacuum initial data for general relativity. The result presents a ``rigidity phenomenon'' for the extrinsic curvature, caused by the non-posi…
