DESCRIPTION:A Floer homology invariant for 3-orbifolds via bordered Floer.
 \n\nUsing bordered Floer\, we construct an invariant for 3-orbifolds Y^orb
  with singular set a knot that generalizes HF-hat for 3-manifolds. We show
  that for a large class of 3-orbifolds the invariant behaves like HF-hat i
 n that the invariant (together with a relative Z_2-grading) categorifies t
 he order of H_1^orb(Y^orb). When Y^orb arises as Dehn surgery on an intege
 r-framed knot in S^3\, we use Jen Hom's {-1\,0\,1}-valued epsilon knot inv
 ariant to prove a rank inequality between the orbifold invariant and HF-ha
 t of the 3-manifold underlying Y^orb.\n
