[Wien] Ab inition and DFT

[ben amara imen]

Dears users

Can someone please  explain the difference between ab initio calculation
and DFT.

As I know , ab initio calculation is based on wave function without any
empirical parameters . DFT is based on density of charge but it uses the
empirical parameters (within Exchange-correlation potentiel PBE , GGA..).

Is it correct ?.

If it is correct , why some papers consider DFT as ab initio calculation.

Thanks


Best regards
