      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 ...

      Ioachim, E.; Charchanti, A.; Charalabopoulos, K.; Tsanou, E.; Briassoulis, E. Ch; Karavasilis, V.; Pavlidis, Nicholas; Agnantis, Niki J. (2002)
      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 ...
