Researcher Finally Solves Math Question Left Unanswered for Over 40 Years

Researchers have solved a long-standing problem in topology by helping classify four-dimensional shapes (4-manifolds) that allow certain types of deformations, known as quasiregular mappings, from Euclidean space. Susanna Heikkilä has made a significant breakthrough in topology, a branch of mathematics concerned with the properties and shapes of geometric surfaces. One of the articles from her [...]
