Zvonimir Janko's Degrees
- PhD Mathematics University of Zagreb
Why Is Zvonimir Janko Influential?
(Suggest an Edit or Addition)According to Wikipedia, Zvonimir Janko was a Croatian mathematician who was the eponym of the Janko groups, sporadic simple groups in group theory. The first few sporadic simple groups were discovered by Émile Léonard Mathieu, which were then called the Mathieu groups. It was after 90 years of the discovery of the last Mathieu group that Zvonimir Janko constructed a new sporadic simple group in 1964. In his honour, this group is now called J1. This discovery launched the modern theory of sporadic groups and it was an important milestone in the classification of finite simple groups.
