Abstract: | We prove here a theorem, which generalizes Grauert's comparison theorem (4], Hauptsatz IIa; cf. also Knorr 7], Vergleichssatz) and which is an analogue of a Grothéndieck's result in Algebraic Geometry (6], Chap. III., 4.1.5). The proof makes essential use of a coherence theorem for sheaves of polynomials: Let X,Y be complex spaces, : X Y a proper holomorphic map and T=(T1,...,TN) a system of indeterminates. Then, for everyO
XT] graded sheafm, all direct image sheaves Rq *
m areYT]-coherent. The proof is as in 2].
