For centuries, one of algebra’s oldest puzzles has remained unsolved—how to find exact answers for higher-degree polynomials, where the variable is raised to the fifth power or more. Mathematicians ...

Two mathematicians have used a new geometric approach in order to address a very old problem in algebra. In school, we often learn how to multiply out and factor polynomial equations like (x² – 1) or ...

Polynomial matrices, whose entries are univariate or multivariate polynomials, furnish a powerful algebraic framework for the analysis and control of linear systems. By extending classical matrix ...
