Query: A Posteriori Error Estimates with Boundary Correction for a Cut Finite
  Element Method   In this work we study a residual based a posteriori error estimation for the
CutFEM method applied to an elliptic model problem. We consider the problem
with non-polygonal boundary and the analysis takes into account the geometry
and data approximation on the boundary. The reliability and efficiency are
theoretically proved. Moreover, constants are robust with respect to how the
domain boundary cuts the mesh.
