Structure preservation and general relativity


we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes.  This includes a request to enter credit card information.

Please note, INI will never contact you over the phone requesting card details. We take all payments via the University of Cambridge Online store

If you have been contacted by this company please contact us as soon as possible.

Workshop Theme 

Numerical relativity--the design, implementation, and study of computational methods for the approximate solution of Einstein's equations--is a powerful approach to understanding the complex behavior of gravitational fields. Einstein's equations are statements about the geometry of space times, based on differential geometric structures such as covariance, symmetries, etc.  For this reason, structure-preserving numerical methods have the potential to bring enormous benefits to numerical relativity.  The development of stable structure-preserving discretization methods for the Einstein equations has thus far proven largely elusive, but it represents a direction with great promise.  The successful contribution of numerical relativity to the LIGO observations in 2015 and since has highlighted the important place of numerical relativity in the new world of gravitational wave astronomy.  Beyond that, numerical investigations into the behavior of gravity in four and higher dimensions in the highly non-linear regime and computational explorations of holograpy both illustrate the significant role of the field to deciphering the full implications of Einstein's theory of relativity. This role raises many particular challenges, for example, the presence of highly non-linear constraints that must be satisfied for a correct solution, the vast length of time and spatial scales associated to problems of practical interest, the development of singularities, and the necessity to introduce spatial boundaries, which, in turn, require constraint-preserving boundary conditions.  All these challenges facing us, together with the recent advances in structure-preserving discretization in other branches of numerical PDE makes this an ideal time to bring together specialists in numerical analysis, computational science, geometry, general relativity, and numerical relativity to discuss and interact in a multidisciplinary environment.

Deadline for applications: 2nd June 2019

GCS programme participants DO NOT need to apply, programme participants with visit dates during GCSW01 will automatically be added to the attendee list.

Please note members of Cambridge University are welcome to turn up and sign in as a non-registered attendee on the day(s) during the workshop and attend the lecture(s). Please note that we cannot provide you with any support including name badge, meals or accommodation.

In addition to visiting the INI, there are multiple ways in which you can participate remotely.
