The computational complexity of polynomial factorization

May 15 to May 19, 2006

at the

American Institute of Mathematics, Palo Alto, California

organized by

Shuhong Gao, Mark van Hoeij, Erich Kaltofen, and Victor Shoup

This workshop, sponsored by AIM and the NSF, will be devoted to algorithms for factoring polynomials. Univariate and multivariate polynomials will be considered, with coefficients from finite fields, the rationals, and the complex numbers. Dense polynomials, where all coefficients are present, will be considered, as well as sparse polynomials that have many zero coefficients.

The problem of factoring polynomials is a classical problem of algebra with classical algorithms due to, for instance, Newton, Puisseux, Eisenstein, Gauss, Kronecker, Hilbert, and Hensel, and modern algorithms that use randomization, lattice basis reduction, baby-steps giant-steps techniques, root power and logarithmic derivates sums, and numerical approximation. Modern algorithms utilize efficient data structures such as straight-line programs and black boxes for evalution. The goal of the workshop is to invent significantly faster new algorithms, or in turn establish hardness of a given factorization problem.

The main topics for the workshop are:

The workshop will differ from typical conferences in some regards. Participants will be invited to suggest open problems and questions before the workshop begins, and these will be posted on the workshop website. These include specific problems on which there is hope of making some progress during the workshop, as well as more ambitious problems which may influence the future activity of the field. Lectures at the workshop will be focused on familiarizing the participants with the background material leading up to specific problems, and the schedule will include discussion and working sessions.

The deadline to apply for support to participate in this workshop has passed.
