cohomology with constant coefficients / with a local system of coefficients
differential cohomology
The de Rham cohomology and Dolbeault cohomology can be viewed as abelian sheaf cohomology theories with coefficients in the sheaf of locally constant functions, respectively holomorphic functions. Spencer cohomology is a generalization of these two cohomologies for the case of the solution sheaf of an arbitrary linear differential operator.
