Query: N Fermion Ground State of Calogero-Sutherland Type Models in Two and
  Higher Dimensions   I obtain the exact ground state of $N$-fermions in $D$-dimensions $(D \geq
2)$ in case the $N$ particles are interacting via long-ranged two-body and
three-body interactions and further they are also interacting via the harmonic
oscillator potential. I also obtain the $N$-fermion ground state in case the
oscillator potential is replaced by an $N$-body Coulomb-like interaction.
