200th Anniversary of the mathematical genius Evariste Galois

Nikola P. Ziapkov

Abstract

 

During his short life Galois invented a theory, which would set the foundations of the contemporary abstract mathematics. He introduced the definitions of groups, normal subgroups and normal field extensions, which gave birth of new branches in mathematics such as group theory, topology, homological algebra. Nowadays these objects are frequently encountered in various applied sciences - coding theory, cryptography, nuclear models in physics, crystallography and many others.
