Abstract
We consider the system of interval-valued fuzzy sets (IVFS) in a universe X and study the cuts of an IVFS. Suppose a left continuous triangular norm is given. The t-norm Based cut (level set) of an IVFS is defined in a way that binds the membership lower bound and membership upper bound function via the triangular norm. This is an extension of usual cuts of IVFS. We show that the system of these cuts fulfills analogical properties as usual systems of cuts. However, it is not possible to reconstruct an IVFS from the system of t-norm Based cuts.
