The Braid Group of Z
نویسنده
چکیده
We define quasi-Garside groups and prove a theorem about them parallel to Garside’s result on the word problem for the usual braid groups. We introduce a group which we call the braid group B of Zn, and which bears some resemblance to mapping class groups. We prove that B is a quasi-Garside group. We give a ‘small presentation’ for B.

Irreducibility of the tensor product of Albeverio's representations of the Braid groups $B_3$ and $B_4$
We consider Albeverio's linear representations of the braid groups $B_3$ and $B_4$. We specialize the indeterminates used in defining these representations to non zero complex numbers. We then consider the tensor products of the representations of $B_3$ and the tensor products of those of $B_4$. We then determine necessary and sufficient conditions that guarantee the irreducibility of th...
متن کاملBraid Monodromy Type and Rational Transformations of Plane Algebraic Curves
We combine the newly discovered technique, which computes explicit formulas for the image of an algebraic curve under rational transformation, with techniques that enable to compute braid monodromies of such curves. We use this combination in order to study properties of the braid monodromy of the image of curves under a given rational transformation. A description of the general method is give...
متن کاملInner products on the Hecke algebra of the braid group
We point out that the Homfly polynomial (that is to say, Ocneanu’s trace functional) contains two polynomial-valued inner products on the Hecke algebra representation of Artin’s braid group. These bear a close connection to the Morton–Franks–Williams inequality. In these structures, the sets of positive, respectively negative permutation braids become orthonormal bases. In the second case, many...
متن کاملPresentations for the Cohomology Rings of Tree Braid Groups
If Γ is a finite graph and n is a natural number, then UCnΓ, the unlabelled configuration space of n points on Γ, is the space of all n-element subsets of Γ. The fundamental group of UCnΓ is the n-strand braid group of Γ, denoted BnΓ. We build on earlier work to compute presentations of the integral cohomology rings H∗(UCnT ;Z), where T is any tree and n is arbitrary. The results suggest that H...
متن کاملKrammer's Representation of the Pure Braid Group, P3
We consider Krammer’s representation of the pure braid group on three strings: P3 → GL 3, Z t±1, q±1 , where t and q are indeterminates. As it was done in the case of the braid group, B3, we specialize the indeterminates t and q to nonzero complex numbers. Then we present our main theorem that gives us a necessary and sufficient condition that guarantees the irreducibility of the complex specia...
