| This relax and cut type approach has shown its numerical efficiency in many combinatorial problems. |
| Accepting a position at Princeton, he attended a course on knot theory by R Fox and from this his interest was aroused in combinatorial group theory. |
| Using a combinatorial code of these proteins, we can tease the stem cells out of very complicated mixtures. |
| Research into questions of this type is still of major importance in combinatorial group theory. |
| We propose a generalization of Sahlqvist formulae to polyadic modal languages by representing modal polyadic languages in a combinatorial style. |
| The group focuses on the combinatorial theory of free groups, and on the solvability of systems of equations. |
