Description

  • Speaker

    Henry Bambury - DGA-MI et Inria Rennes

We give a strict generalisation of the LLL algorithm over number fields, based on the reduction theory of  $GL(n)$ over the adele ring of a number field. Our algorithm is free of heuristics, with rigorous bounds on output quality and complexity.

 

-- based on joint work with Seungki Kim, Changmin Lee and Phong Nguyen --
