Niels Obers<\/strong> (NORDITA)<\/p>\n\n\n\n Title:<\/strong> Non-relativistic gravity and strings<\/p>\n\n\n\n Abstract:<\/strong> I will start by motivating the recent interest in non-relativistic gravity and strings. These build on recent advances and generalizations of Newton-Cartan geometry, originally introduced by Cartan to geometrize Newtonian gravity. I will then present an action principle for non-relativistic gravity and its coupling to matter, including its Newtonian limit. This requires a new notion of NC geometry, which naturally arises in a covariant 1\/c expansion of general relativity, with c being the speed of light. The corresponding non-relativistic truncation of general relativity goes beyond Newtonian gravity and is able to correctly describe gravitational time dilation. Finally, I will discuss how non-relativistic geometry appears in connection to non-relativistic strings and limits of the AdS\/CFT correspondence. <\/p>\n\n\n\n Meeting information: Slides are available at You can watch the recording at On June 11 we will have a seminar by Niels Obers (NORDITA) Title: Non-relativistic gravity and strings Abstract: I will start by motivating the recent interest in non-relativistic gravity and strings.
