報告摘要: In my talk we recall some definitions from Knot Theory, Braid Theory and the construction of J. Wu and F. Cohen which connects braid groups and homotopy groups of 2-sphere. In more detail we discuss singular braid groups and its subgroup of pure singular braid group. We describe presentation of these groups and linear representation.
