abstract = {The relation of the recently proposed E(5) critical point symmetry with the
interacting boson model is investigated. The large-N limit of the interacting
boson model at the critical point in the transition from U(5) to O(6) is ob-
tained by solving the Richardson equations. It is shown explicitly that this
algebraic calculation leads to the same results as the solution of the Bohr
differential equation with a  β4 potential.},
