Dear all

is there any formal/consistency reason not to use a relativistic  
LDA/GGA ground
state (scalar relativistivistic / spin-orbit) previous to a GW  
quasiparticle correction? In the first-order perturbation expresion  
for the QP correction,
would you need a relativistic Sigma?

for instance, this would impose some limitations on whether scalar  
relativistic
pseudopotentials should be used for such applications...(probably  
relat-paw as well?)
