UNCG Summer School in Computational Number Theory 2018

Algorithms for Extensions of Large Degree

summer school 2017 poster From May 28 to June 1, 2018, the University of North Carolina at Greensboro will host the UNCG Summer School in Computational Number Theory: Algorithms for Extensions of Large Degree.

Algorithms for extensions of global and local fields are the backbone of computational number theory. Improvements in computing power have made it feasible to conduct computations in larger and larger degree. As the complexity of algorithms for field extensions depends on the degree of the extensions, this has increased the interest in asymptotically fast algorithms. Among others we will consider algorithms for integral bases computation and ideal arithmetic.
