Families of cyclic coverings of the projective line: We consider the family of cyclic coverings of the projective line with fixed ramification data, and degree. The monodromy representation associated to these data is closely related to the ``Gassner representation" of the pure braid group, and we characterise the cases when the monodromy group is a product of non-uniform higher rank arithmetic groups.
