      Detection of cavities using the method of fundamental solutions 

      Karageorghis, Andreas; Lesnic, D. (2009)
      The determination of the boundary of a cavity, defined here as a perfectly insulated inclusion, within a conducting medium from a single voltage and current flux measurements on the accessible boundary of the medium, can ...

      Sub-Laplacians with drift on Lie groups of polynomial volume growth 

      Alexopoulos, Georgios K. (2002)
      We prove a parabolic Harnack inequality for a centered sub-Laplacian L on a connected Lie group G of polynomial volume growth by using ideas from Homogenisation theory and by adapting the method of Krylov and Safonov. We ...
