Abstract
Copulas with given diagonals have been studied in [5, 11]. In [2, 6, 12] smallest and greatest (quasi-)copulas with given diagonals are constructed. Both (two-dimensional) copulas and quasi-copulas are special cases of binary 1-Lipschitz aggregation operators [3, 9]. We give constructions for smallest and greatest 1-Lipschitz aggregation operators with given diagonals, allowing us to obtain most results of [12] on (quasi-)copulas with given diagonals as special cases. In particular, the smallest (quasi-)copula with a given diagonal coincides with the smallest 1-Lipschitz aggregation operator with that diagonal.
