abstract = {<p style="text-align: justify;">We first propose an adaptive immersed finite element method based on the a posteriori
error estimate for solving elliptic equations with non-homogeneous boundary conditions in general
Lipschitz domains. The underlying finite element mesh need not fit the boundary of the domain.
Optimal a priori error estimate of the proposed immersed finite element method is proved. The
immersed finite element method is then used to solve parabolic problems in time variable domains
together with an arbitrary Lagrangian-Eulerian (ALE) time discretization scheme. An a posteriori
error estimate for the fully discrete immersed finite element method is derived which can be used
to adaptively update the time step sizes and finite element meshes at each time step. Numerical
experiments are reported to support the theoretical results.</p>},
