A new family of trivariate proper quasi-copulas
In this paper, we provide a new family of trivariate proper quasi-copulas. As an application, we show that W-3 - the best-possible lower bound for the set of trivariate quasicopulas (and copulas) - is the limit member of this family, showing how the mass of W-3 is distributed on the plane x + y + z = 2 of [0, 1](3) in an easy manner, and providing the generalization of this result to n dimensions.
