Covariant Symplectic Structure and Conserved Charges of Topologically Massive Gravity
Caner Nazaroglu, Yavuz Nutku, Bayram Tekin
We present the covariant symplectic structure of the Topologically Massive Gravity and find a compact expression for the conserved charges of generic spacetimes with Killing symmet…
The parton model
O. W. Greenberg
I give a brief review of the parton model.
Self-dual gravity is completely integrable
Y. Nutku, M. B. Sheftel, J. Kalayci +1
We discover multi-Hamiltonian structure of complex Monge-Ampere equation (CMA) set in a real first-order two-component form. Therefore, by Magri's theorem this is a completely inte…
Hamiltonian structure of the complex Monge-Ampère equation
Y. Nutku, M. B. Sheftel
We discover Hamiltonian structure of the complex Monge-Amp`ere equation when written in a first order two-component form. We present Lagrangian and Hamiltonian functions, a symplec…
Lift of noninvariant solutions of heavenly equations from three to four dimensions and new ultra-hyperbolic metrics
A. A. Malykh, Y. Nutku, M. B. Sheftel
We demonstrate that partner symmetries provide a lift of noninvariant solutions of three-dimensional Boyer-Finley equation to noninvariant solutions of four-dimensional hyperbolic…
What is the present-day status of The Copernican Principle?
Y. Nutku
I point out that according to the Copernican principle our universe is not unique. The way to make sense out of this statement is for us to construct a gravitational instanton that…
