Linear perturbations of quaternionic metrics
We extend the twistor methods developed in our earlier work on linear deformations of hyperkähler manifolds [1] to the case of quaternionic-Kähler manifolds. Via Swann’s construction, deformations of a 4d-dimensional quaternionic-Kähler manifold M are in one-to-one correspondence with deformations of its 4d+ 4-dimensional hyperkähler cone S. The latter can be encoded in variations of the comple...
متن کاملLinear perturbations of hyperkähler metrics
We study general linear perturbations of a class of 4d real-dimensional hyperkähler manifolds obtainable by the (generalized) Legendre transform method. Using twistor methods, we show that deformations can be encoded in a set of holomorphic functions of 2d + 1 variables, as opposed to the functions of d + 1 variables controlling the unperturbed metric. Such deformations generically break all tr...
متن کاملThe probability of neural connexions
J In some areas of a nervous system there is no obvious plan of connexions. I f it is assumed, first, that in these areas fibre growth is random, and secondly, that connexions are formed if axon and dendrite approach within a critical distance, there are certain mathematical consequences. If fibre density is defined and measured in a particular way it is possible to derive a formula for the ave...

15 صفحه اولBACKREACTION OF LINEAR PERTURBATIONS AND DARK ENERGYa
The coincidence problem. Perhaps the most surprising observation in modern cosmology is that the expansion of the universe has apparently started to accelerate in the recent past, at a redshift of probably less than one. This phenomenon has usually been interpreted in the context of a homogeneous and isotropic model of the universe. The acceleration can then be accommodated only by modifying gr...
