Estimates for derivatives of the Green functions for noncoercive differential operators on homogeneous manifolds of negative curvature (Q1404339)

The paper deals with weakly coercive operators in Ancona terminology on homogeneous manifolds of negative curvature being a semi-direct product of a nilpotent Lie group \(N\) and \(A=R^+\). For the Green function of such an operator some estimates for the derivatives with respect to the \(N\)- and \(A\)-variables are obtained by some probabilistic and analytic machinery.
