*Spaces in which compact subsets are closed and the lattice of $\bold T_1$-topologies on a set *

Comment.Math.Univ.Carolinae 43,4 (2002) 641-652. **Abstract:**We obtain some new properties of the class of KC-spaces, that is, those topological spaces in which compact sets are closed. The results are used to generalize theorems of Anderson [1] and Steiner and Steiner [12] concerning complementation in the lattice of $T_1$-topologies on a set $X$.

**Keywords:** KC-space, $T_1$-complementary topology, $T_1$-independent, sequential space

**AMS Subject Classification:** Primary 54A10; Secondary 54D10, 54D25, 54D55
