Query: T-duality and entanglement entropy for NS five-branes   In this work an algorithm is proposed to calculate entropy for field theories
living on NS five branes, which gives a result invariant under T-duality. This
is a deformation of the well known Ryu-Takayanagi formula, which takes into
account dependence of localized backgrounds for the branes on winding modes of
strings.
