“…Beside b-adic expansions and continued fraction expansions many other expansions of real number are studied. We have ergodic and dimension theoretical results on β-expansions [29,2], Cantor series expansions [9,16,1], Engel-expansions [10,31,12], Lüroth-expansions [20,4], multiple-base expansions [25,25,22,18] and others. In this paper we introduce a new family of expansions of real numbers which is given essentially by the expression in the abstract.…”
