| They worked on topics such as soluble groups, combinatorics, and matrix theory. |
| Is any computing unrelated to quantum computing now a pointless exercise in combinatorics? |
| The problems which attracted him most were problems in combinatorics, graph theory, and number theory. |
| His early works range over number theory, statistics, combinatorics, game theory, as well as his principal interest of commutative algebra. |
| His basic research contributions span complex analysis, mathematical physics, probability theory, geometry, and combinatorics. |
| The reason is a topic for another note, on the limitations of combinatorics in geometry. |
