Abstract
We characterize those (continuously-normed) Banach bundles with compact Hausdorff base whose spaces of global continuous sections are topologically finitely-generated over the function algebra , answering a question of I. Gogi\'c's and extending analogous work for metrizable . Conditions equivalent to topological finite generation include: (a) the requirement that be locally trivial and of finite type along locally closed and relatively strata in a finite stratification of ; (b) the decomposability of arbitrary elements in , as sums of products in for some fixed ; (c) the analogous decomposability requirement for maximal Banach-module tensor products or (d) equivalently, only for .
