In this paper, we consider a hypernear-ring R and introduce the concept of an interval-valued fuzzy sub-hypernear-ring with respect to t-norm T (t-conorm S). A necessary and sufficient condition for an interval-valued fuzzy subset to be an interval-valued fuzzy sub-hypernear-ring is given and its basic properties are discussed. Also, we consider the fundamental relation gamma* on a hypernear-ring R and prove a fundamental theorem concerning the near-ring R/gamma*.
