Additive Complexity and the Roots of Polynomials Over Number Fields and p-adic Fields | | J. Maurice Rojas

17 Dec 2001 | | Subject: | Number Theory; Combinatorics MSC-class: Number Theory; Complexity Theory | math.NT math.CO | | Abstract: | Consider any nonzero univariate polynomial with rational coefficients, presented as an elementary algebraic expression (using only integer exponents). Letting sigma(f) denotes the additive complexity of f, we show that the number of rational roots of f is no more than 15 + sigma(f)^2 (24.01)^{sigma(f)} sigma(f)!. This provides a sharper arithmetic analogue of earlier results of Dima Grigoriev and Jean-Jacques Risler, which gave a bound of C^{sigma(f)^2} for the number of real roots of f, for some constant C with 1 | | Source: | arXiv, math.NT/0201154 | | Services: | Forum | Review | PDF | Favorites | |
