The very self-contained book "Coherent Analytic Sheaves" answers these (in the affirmative) and many other related questions. (A more transparent definition of finiteness in the connected manifold setting is being either proper with finite fibers or being "classified" by a coherent sheaf of $O_Y$-algebras that is locally free of finite rank; equivalences among possible definitions of analytic finiteness are much deeper than in the algebraic theory.) | |
