Hair theorem

Hairy ball theorem - Wikipedia. The hairy ball theorem may be successfully applied for the analysis of the propagation of electromagnetic waves, in the case when the wave-front forms a surface, topologically equivalent to a sphere (the surface possessing the Euler characteristic χ = 2). See more

No-hair theorem - Wikipedia hair theorem. In Violation of Einstein, Black Holes Might Have ‘Hair’ hair theorem.

The no-hair theorem can be tested by measuring (at least) three different multipole moments, which have to be related by expression if this theorem is correct (Ryan 1995).

The notion of quantum hair allows information about what goes into a .. Testing the No-Hair Theorem with Sgr A* - Hindawi. The no-hair theorem characterizes the fundamental nature of black holes in general relativity. This theorem can be tested observationally by measuring the mass and spin of a black hole as well as its quadrupole moment, which may deviate from the expected Kerr value. Sgr A*, the supermassive black hole at the center of the Milky Way, is a …. TESTING THE NO-HAIR THEOREM WITH OBSERVATIONS IN … hair theorem. According to the no-hair theorem, an astrophysical black hole is uniquely described by only two quantities, the mass and the spin. In this series of papers, we investigate a framework for testing the no-hair theorem with observations of black holes in the electromagnetic spectrum hair theorem. We formulate our approach in terms of a parametric

A no-hair theorem for black holes in gravity - IOPscience. Here we show that our no-hair theorem also can discard asymptotic de Sitter stationary and axisymmetric non-trivial black holes. The novelty is that this no-hair theorem is built without resorting to known mapping between f(R) gravity and scalartensor theory hair theorem

No hair theorem for bound-state massless static scalar fields …. For massive scalar fields, a no hair theorem for Neumann compact stars was proved by us in a previous paper, where the nonzero scalar field mass condition is essential in the proof. In the present work, for massless scalar fields, we prove a no hair theorem, which claims that bound-state massless static scalar fields cannot exist outside ….

. The ringdown is simply the black hole formed in the merger settling down to a final stationary form. According to the no-hair theorem, this stationary form has to be described by the Kerr family of metrics described by the mass and angular momentum of the final black hole (since the intitial system is assumed to be electrically neutral)..
