چکیده انگلیسی

Let (K,v)(K,v) be a discrete rank one valued field with valuation ring RvRv. Let L/KL/K be a finite extension such that the integral closure S   of RvRv in L   is a finitely generated RvRv-module. Under a certain condition of v  -regularity, we obtain some results regarding the explicit computation of RvRv-bases of S, thereby generalizing similar results that had been obtained for algebraic number fields in El Fadil et al. (2012) [7]. The classical Theorem of Index of Ore is also extended to arbitrary discrete valued fields. We give a simple counter example to point out an error in the main result of Montes and Nart (1992) [12] related to the Theorem of Index and give an additional necessary and sufficient condition for this result to be valid.
