On the ternary semigroups of homeomorphic transformations of bounded closed sets with nonempty interior of finite-dimensional Euclidean spaces

Ternary semigroup is a universal algebra with an associative ternary operation. We give a characterization of bounded closed sets with nonempty interior of finite-dimensional Euclidean spaces by ternary semigroups of pairs of homeomorphic transformations.
