One of the 'small' quantum (super-)groups provides an interesting polynomial invariant of knots and links, known as the Links-Gould polynomial. As opposed to its more famous cousins, (the Alexander, Jones, Homfly-pt and Kaufmann polynomials), its natural algebraic counterpart, which should be a quotient of the group algebra of the braid group was not understood at all. I will present recent progress on this subject, obtained in a joint work with E. Wagner. This progress is based on remarkable properties of the cubic quotients of the braid groups, which are of independent interest.
