The strong-interaction limit of the Kohn-Sham DFT exchange-correlation functional has a mathematical structure radically different than the one of standard approximated functionals. Instead of the usual ingredients (local density, local density gradient, Kohn-Sham kinetic energy density, occupied orbitals, etc...) in this limit certain integrals of the density appear.

I will discuss some recent exact results on this limit and approximations inspired to its mathematical structure, illustrating applications and perspectives in low-dimensional physics and in chemistry.
