Query: Regularization of a strong-weak duality between pointlike interactions
  in one dimension   Pointlike interactions between bosons in 1D are related to pointlike
interactions between fermions through the Girardeau mapping. This mapping is a
strong-weak duality since the coupling constants in the bosonic and fermionic
cases are inversely proportional to each other. We present a regularization of
these pointlike interactions that preserves the strong-weak duality, contrary
to previously known regularizations. This is proven rigorously. This allows one
to use this duality perturbatively and we illustrate it in the Lieb-Liniger
model at strong coupling.
