Definition of Empty Set. An Empty Set is a set with no elements. It can be symbolized by {} or Ã¸. The solution set for an equation that has no solution is also called an empty set.It is also called a null set. A = {2, 6, 8} and B = {3, 5, 7}. Let C represent the intersection of the sets A and B. C = {}, a null set, because there is no element common between the two sets.
Answer Wiki. Standard Zermelo-Fraenkel (ZF) set theory defines zero as being the empty set, or in mathematical notation 0 = {}. Though it can also be defined as the set that only contains the empty set, but that's somewhat pointless for this situation (I just thought I'd mention it in case someone else uses this definition instead).
