Query: Harmonic Maass-Jacobi forms with singularities and a theta-like
  decomposition   Real-analytic Jacobi forms play key roles in different areas of mathematics
and physics, but a satisfactory theory of such Jacobi forms has been lacking.
In this paper, we fill this gap by introducing a space of harmonic Maass-Jacobi
forms with singularities which includes the real-analytic Jacobi forms from
Zwegers's PhD thesis. We provide several structure results for the space of
such Jacobi forms, and we employ Zwegers's $\widehat\mu$-functions to establish
a theta-like decomposition.
