The literature about K3 surfaces is extensive. However,Let us consider the fact that the zero locus of any smooth homogeneous degree 4 equation is a K3 surface.
Let $R$ the quotient ring of a homogeneous polynomial in $4$ variables and degree $4$.
I am not being succesfull to find anything related to the study of derivations and locally nilpotent derivations on these surfacessort of ring. What could be a reference for
- a description of the derivations on these surfaces$R$?
- a description of the locally nilpotent derivations (if there exists) on these surfaces$R$?
- a description of the automorphism groups of these surfaces$R$?
- any condition for the group of automorphisms of these surfaces$R$ to be finite/finitely generated?
