The Gassner representation of the pure braid group to GLn(Z[Z ]) can be extended to give a representation of the concordance group of n-strand string links to GLn(F ), where F is the field of quotients of Z[Z ], F = Q(t1, · · · , tn); this was first observed by Le Dimet. Here we give a cohomological interpretation of this extension. Our first application is to prove that the representation is h...

two forage species alfalfa (medicago sativa), and sainfoin (onobrychis viciifolia scop.), at two consecutive growing season (spring and summer), were studied for their chemical composition and in vitro gas production characteristics. data on cumulative gas production (ml gas/g dm) were fitted to the non-sigmoidal model, and for evaluation of model, the concordance correlation coefficient (ccc) ...

A cobordism between links in thickened surfaces consists of a surface $ S and $3$-manifold $M $, with properly embedded M \times I $. We show that there exist such if $(S,M) is them which simple, then must be complex. That is, are cases low complexity the does not imply $3$-manifold. Specifically, we concordant concordance can only realised by passing through thickenings higher genus surfaces. ...
