| On the other hand, in quantum mechanics you will deal more with algebraic techniques. |
| Instead of taking an algebraic approach, however, Halton used a shortcut inspired by the geometry of paths traced by rays of light. |
| According to Rotman, the justification of homological algebra is that it eventually proved useful in solving purely algebraic problems. |
| The theorem states that all central division algebras over algebraic number fields are cyclic algebras. |
| He had a distinguished career as a math professor, specializing in algebra, algebraic geometry and number theory. |
| Herbrand also worked on field theory considering abelian extensions of algebraic number fields. |
