| contents | We establish a fundamental theorem of orders (FTO) which allows us to express all orders uniquely as an intersection of `irreducible orders' along which the index and the conductor distributes multiplicatively.
We define a subclass of Irreducible orders named Pseudo maximal orders. We then consider orders (called Sudo maximal orders) whose decomposition under FTO contains only Pseudo maximal orders. These rings can be seen as being ``close" to being maximal (ring of integers) and thus there is a limited number of them with bounded index (by X). We give an upper bound for this quantity. We then show that all polynomials which can be sieved using only the Ekedahl sieve correspond to Sudo Maximal Orders. We use this understanding to get a weighted count for the number of number-fields with fixed degree and bounded discriminant using the concept of weakly divisible rings. |
