Polycritical Gravities
We present higher-derivative gravities that propagate an arbitrary number of gravitons of different mass on (A)dS backgrounds. These theories have multiple critical points, at which the masses degenerate and the graviton energies are non-negative. For six derivatives and higher there are critical points with positive energy.
متن کاملLecture Notes on Chern-simons (super-)gravities
This is intended to be a broad introduction to Chern-Simons gravity and supergravity. The motivation for these theories lies in the desire to have a gauge invariant system –with a fiber bundle formulation– in more than three dimensions, which could provide a firm ground for constructing a quantum theory of the gravitational field. The starting point is a gravitational action which generalizes t...
متن کاملTwisted World-Sheet Gravities
This is the first in a series of papers in which I investigate the orbifolds of permutation-type as candidates for new physical string systems at multiples of critical closed-string central charges. Examples include the bosonic orientation orbifolds, the bosonic permutation orbifolds and others, as well as superstring extensions. In this paper I use the extended (twisted) Virasoro algebras of t...
متن کاملOn Elementary Unitary and Φ-unitary Transformations
We introduce a simple uniform structure of elementary Φ-unitary matrices. Elementary Φ-unitary transformations are the extentions of Householder transformations in real and complex spaces with a definite or an indefinite inner product induced by a nonsingular signature matrix Φ. The extentions are found useful in the computations of complex matrices or special structured matrices. For two (comp...
متن کاملDimensionally Challenged Gravities
It is a pleasure to dedicate this little travelogue/catalogue of exotic gravity models to John Stachel, whose loyalty to the D=4 Einstein cause is too steadfast to be subverted by reading it. Once unleashed by general relativity, dynamical geometry has become a fertile playground for generalization in many directions beyond Einstein’s D=4 Ricci-flat choice. This trend has intensified with strin...
