The best known unconditional deterministic complexity bound for computing the prime factorization of an integer N is O(Mint(N 1/4 logN)), where Mint(k) denotes the cost of multiplying k-bit integers. This result is due to Bostan–Gaudry–Schost, following the Pollard–Strassen approach. We show that this bound can be improved by a factor of √

Whatever option is chosen, the discourse on ICT gives foundation to the tools as training or learning outlines. e still are in the "learning" of the e-learning where the "e" becomes subordinate. However, the ICTs are not on...

Recently, Bostan and his coauthors investigated lattice walks restricted to the non-negative octant N3. For the 35548 non-trivial models with at most six steps, they found that many models are associated to a group of order at least 200 and conjectured these groups were in fact infinite groups. In this paper, we first confirm these conjectures and then consider the non-D-finite property of the ...
