Évariste Galois mepụtara okwu "otu" ma guzobe njikọ, nke a maara ugbu a dị ka Galois theory, n'etiti usoro ọmụmụ nke ìgwè na-eto eto na usoro ọmụmụ nke Galois. Na geometry, ìgwè ndị mbụ ghọrọ ihe dị mkpa na geometry projective na mgbe e mesịrị, na-abụghị Euclidean geometry. Felix Klein's Erlangen program kwuru na usoro ọmụmụ nke geometry bụ ụkpụrụ nhazi
