Let be a rational prime, be a finite extension of the field of -adic numbers, and let be a totally ramified cyclic extension of degree . Restrict the first ramification number of to about half of its possible values, where denotes the absolute ramification index of . Under this loose condition, we explicitly determine the -module structure of the ring of integers of , where denotes the -adic integers and denotes the Galois group Gal. In the process of determining...
