The Mathematical Institute and Department of Statistics are internationally renowned departments which work closely together and deliver joint undergraduate and postgraduate degrees. Our mathematical research, impact and environment have twice been ranked first in the UK, in the 2021 and 2014 Research Excellence Framework exercises, a government review of research in all UK universities. The two departments are committed both to academic excellence and the opportunity to study for all enthusiastic and gifted prospective undergraduates.

How to Count States in Gravity
Tom Yildirim
( Oxford)
Abstract
In this talk we will construct a basis of quantum gravity states by cutting the Euclidean path integral. These states are made by inserting heavy dust shell operators on the asymptotic boundary. We will use this basis to resolve two puzzles :
(1) The two boundary gravity Hilbert space seemingly does not factorise, which is in tension with holography.
(2) Gibbons and Hawking proposed the gravity thermal partition function is computed by the euclidean path integral with a periodic time boundary condition. Why is does this perform a trace over gravity states?
To resolve these puzzles we will introduce some tricks that simply the evaluation of the gravity path integral in the saddle point approximation.
Road closures that will happen just after Gate 7 from 14th July for 2.5 weeks, possibly 3 weeks:
There will be pedestrian access down the side of maths to the East west link (next to Somerville)
No pedestrian access down past Gibson/ Harkness/ GTC during this time
Vehicle access will still be available from Gate 7 to car lifts and the revolving maths doors/ disabled parking
