On nodal Enriques surfaces and quartic double solids
Colin Ingalls, Alexander Kuznetsov
We consider the class of singular double coverings $X \to \PP^3$ ramified in the degeneration locus of a family of 2-dimensional quadrics. These are precisely the quartic doubl…
Killing tensors in pp-wave spacetimes
Aidan J Keane, Brian O J Tupper
The formal solution of the second order Killing tensor equations for the general pp-wave spacetime is given. The Killing tensor equations are integrated fully for some specific pp-…
Modified general relativity as a model for quantum gravitational collapse
Andreas Kreienbuehl, Viqar Husain, Sanjeev S. Seahra
We study a class of Hamiltonian deformations of the massless Einstein-Klein-Gordon system in spherical symmetry for which the Dirac constraint algebra closes. The system may be reg…
Duality of force laws and Conformal transformations
Dawood Kothawala
As was first noted by Isaac Newton, the two most famous ellipses of classical mechanics, arising out of the force laws F~r and F~1/r^2, can be mapped onto each other by changing th…
The thermodynamic structure of Einstein tensor
Dawood Kothawala
We analyze the generic structure of Einstein tensor projected onto a 2-D spacelike surface S defined by unit timelike and spacelike vectors u_i and n_i respectively, which describe…
Refined Wall-Crossing, Free Fermions and Crystal Melting
Haitao Liu, Jie Yang
In this paper, we use an M-theory model to conjecture the refined reminiscence of the OSV formula connecting the refined topological string partition function with the refined BPS…
