AbstractAn approximation space is a key concept in rough set theory, which plays an important role to approximate reasoning about data. An interval-valued fuzzy (IVF, for short) approximation space is an approximation space in the IVF environment. In this paper, IVF rough approximation operators are investigated with topological structures of IVF approximation spaces given
