The Odd story of alpha-prime corrections

I will discuss the T-duality structure of the first order alpha-prime corrections in the string effective actions. Deformations of Double Field Theory provide a covariant gauge symmetry principle that organizes these corrections and allows to obtain the four derivative corrections to bosonic and heterotic strings, HSZ theory, half-maximal gauged supergravities, etc.
