The study of curve arrangements in the framework of algebraic geometry examines configurations of algebraic curves—ranging from lines to higher degree entities—in projective spaces, where intricate ...

Michael Freedman’s momentous 1981 proof of the four-dimensional Poincaré conjecture was on the verge of being lost. The editors of a new book are trying to save it. One of the most important pieces of ...

The question of how to control a robotic welding torch to trace the joint between two cylindrical pipes can be reduced to a problem in algebra. Maple can be utilised to derive the parametric equations ...
