Abstract
In this paper we study the kernel of the homomorphism \(B_{g,n} \rightarrow B_n\) of the braid group \(B_{g,n}\) in the handlebody \(\mathscr {H}_g\) to the braid group \(B_n\). We prove that this kernel is semi-direct product of free groups. Also, we introduce an algebra \(H_{g,n}(q)\), which is some analog of the Hecke algebra \(H_n(q)\), constructed by the braid groupĀ \(B_n\).
