Left-continuity of t-norms on the unit interval [0, 1] is equivalent to the property of suppreserving, but this equivalence does not hold for t-norms on the n-dimensional Euclidean cube [0, 1] n for n β₯ 2. Based on the concept of direct poset we prove that a t-norm on [0, 1] n is left-continuous if
