DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AnLy/69/">Hi
 gher-derivative Solution Generation with String Dualities</a>\nby Robert S
 askowski (Tianjin U.) as part of AnLy Strings and Fields online seminars\n
 \n\nAbstract\nIn this talk\, I will discuss recent progress in the use of 
 T- and U-dualities to generate higher-derivative solutions. In particular\
 , I will show how to use an O(2\,1) boost to obtain the four-derivative co
 rrections to the four-dimensional Kerr-Sen solution in heterotic supergrav
 ity for two choices of four-derivative action\, one of which corresponds t
 o the usual Bergshoeff-de Roo action. In the process\, we will see that th
 ere is a consistent truncation that can be used to restore the heterotic g
 auge fields. I will then use a simple group theory argument to show the fa
 ilure of U-duality for solution generation at the four-derivative level in
  the case of the G_{2(2)} coset model obtained from minimal five-dimension
 al supergravity.\n
