Immune mathematics

Our friends lymphocytes and their enemies Guarding the health of any living organism is the immune system protecting it from viruses, bacteria and parasites that cause disease. The main weapon of the immune system — lymphocytes, blood cells that recognize Read more

In the 30-ies of XX century geometer Harold Coxeter developed the theory of groups of reflections in Euclidean spaces and on spheres. Such groups can be obtained as the group generated by reflections in faces of a polytope of any Read more

Mutual penetration of different areas of mathematics not only leads to remarkable new results — which fully manifested Margulis and Furstenberg — but also of great aesthetic and intellectual experience even when proved facts are well known. One of the Read more
