Quaest. Math. 20, No. 3, 423-429 (1997).

The authors introduce a construction of an \((L,M)\)-topology in terms of a decreasing family of \((L,M)\)-topologies. It is shown that the level topologies of the resulting \((L,M)\)-topology can also be constructed from those of the members of the family. An \((L,M)\)-topology, a level \(L\)-topology, the construction as well as the result are generalizations of [A. P. Shostak, Mat. Vesn. 41, No. 1, 51-64 (1989; Zbl 0705.54007)]. Here instead of two unit intervals complete lattices \(L\), \(M\) with \(M\) completely distributive are used.
