Title: Sturmian comparison results for quasilinear elliptic equations
      in $R^n$

Author: Tadie (Universitetsparken 5, Copenhagen, Denmark)
 
Abstract:
 We obtain Sturmian comparison results for the nonnegative solutions
 to Dirichlet problems associated with  $p$-Laplacian operators.
 From  Picone-type identities  [4,9],
 we obtain results comparing solutions of two types of equations.
 We also present results related to those operators using
 Picone-type identities.
