Human immunodeficiency virus nephropathy (HIVN) continues to challenge nephrologic consultative services at major urban institutions. Although noted in the literature, the decreased incidence of peripheral edema in HIVN has been unexplained to date. In HIV patients, total proteins frequently are found to be elevated due to an elevated globulin fraction. The(More)
We present an algorithm for computing discriminants and prime ideal decomposition in number fields. The algorithm is a refinement of a p-adic factorization method based on Newton polygons of higher order. The running-time and memory requirements of the algorithm appear to be very good: for a given prime number p, it computes the p-valuation of the(More)
Let p be a prime number. We present an algorithm that computes p-integral bases in number fields. The algorithm is obtained as a by-product of a p-adic factorization method based on Newton polygons of higher order. The running-time of the algorithm appears to be very good: it computes the 2-integral basis of a number field of degree 1152 in a few seconds.
Let f (x) be a separable polynomial over a local field. Montes algorithm computes certain approximations to the different irreducible factors of f (x), with strong arithmetic properties. In this paper we develop an algorithm to improve any one of these approximations , till a prescribed precision is attained. The most natural application of this "(More)
Let K be the number field determined by a monic irreducible polynomial f (x) with integer coefficients. In previous papers we parameterized the prime ideals of K in terms of certain invariants attached to Newton polygons of higher order of f (x). In this paper we show how to carry out the basic operations on fractional ideals of K in terms of these(More)
