      Centered densities on Lie groups of polynomial volume growth 

      Alexopoulos, Georgios K. (2002)
      We study the asymptotic behavior of the convolution powers φ*n =φ*φ*⋯φ* of a centered density φ on a connected Lie group G of polynomial volume growth. The main tool is a Harnack inequality which is proved by using ideas ...

      Microvessel density (MVD) was analyzed for associations with clinical and pathological factors as well as with other potential known prognostic factors such as: steroid receptor content (ER, PgR), p53 and proliferation ...
