An (a, d)-edge-antimagic total labeling of a graph G is a bijection f from V(G) ∪ E(G) onto {1, 2,..., |V(G)| + |E(G)|} with the property that the edge-weight set {f(x) + f(xy) + f(y) | xy ∈ E(G)} is equal to {a, a + d, a + 2d,... ,a + (|E(G)| - 1)d} for two integers a 〉 0 and d ≥ 0. An (a,d)-edge- antimagic total labeling is called super if the smMlest possible labels appear on the vertices. In this paper, we completely settle the problem of the super (a, d)-edge-antimagic total labeling of the complete bipartite graph [(m,n and obtain the following results: the graph t(m,n has a super (a, d)-edge-antimagic total labeling if and only if either (i) m = 1, n = 1, and d ≥ 0, or (ii) m = 1, n≥2 (orn=1 and m≥2),and d ∈{0,1,2},or (iii) m=l,n=2 (orn=1 and m = 2), and d= 3, or (iv) m,n≥2, and d=1
