I analyze this problem with the help of the tensionless string on AdS3xS3xT4 (with one unit of NS-NS flux) that was recently understood to be dual to the symmetric orbifold of T4. I argue that large stringy corrections around a fixed background can be interpreted as different semiclassical geometries, thus making a sum over semi-classical geometries superfluous.<\/p>\n\n\n\n<p>Meeting information:<br><strong>11th of March 14:30 Italian Time<br>Zoom Meeting <a href=\"https:\/\/l.infn.it\/stringwebseminar\">https:\/\/l.infn.it\/stringwebseminar<\/a><\/strong><\/p>\n\n\n\n<p>Slides are available at<br><a href=\"https:\/\/pandora.infn.it\/public\/95b99e\">https:\/\/pandora.infn.it\/public\/95b99e<\/a><\/p>\n\n\n\n<p>You can watch the recording at<br><a href=\"https:\/\/pandora.infn.it\/public\/00cf45\">https:\/\/pandora.infn.it\/public\/00cf45<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>On March 11 we will have a seminar by Lorenz Eberhardt (IAS) Title: Summing over geometries in string theory Abstract: I discuss the question how string theory achieves a sum over bulk geometries with fixed asymptotic boundary conditions.
