Generalised T-dualities\, which include non-abelian and Poisson-Lie T-duality\, apply to a significantly larger cl ass of target spaces with a wide range of applications. Classically they a re on an equal footing with abelian T-duality\, but their quantum correcti ons are much more mysterious and mostly unexplored. I will review the main problems which have to be solved to make progress in this direction. Afte rwards\, I demonstrate how recently explored connections between generalis ed T-dualities\, double field theory\, and consistent truncations allow to prove that two-loop RG flows are preserved under these dualities. We will discuss the implications of this result and emphasise how the intriguing mathematical structures that govern all the currentapplications influence quantum corrections in a highly non-trivial way.\n LOCATION:https://researchseminars.org/talk/EGSS/20/ END:VEVENT END:VCALENDAR
