Daniel Heineman Prize: The Quest for Quantum Gravity
... • If one imposes only two of the three consistency conditions, one can find many theories of quantum gravity. • Many attempts give up Lorentz invariance at the start, and it has even been argued that this is a necessary feature of quantum gravity. • It is hard to see how the successes of Special Rel ...

Hyperfunction Geometry
... Hyper-function geometry An old (1980) program of mine is to develop hyperfunction geometry. It was motivated by work of Hawking on Euclidean Quantum Gravity and of Penrose on Twistor Quantization. Hawking considers complex 4-manifolds. To begin with, they admit Lorentzian sections. But he goes on to ...
