Katz, Daniel Note on projective modules. (English) Zbl 0733.13003 Math. Pannonica 1, No. 2, 3-5 (1990). The author presents an elementary proof of the fact that any projective module of finite constant rank (all the localizations at prime ideals have the same (finite) rank) over a commutative ring R is finitely generated.
