Independent domination in the graph defined by two consecutive levels of the -cube
Thomas Kalinowski, Uwe Leck
Fix a positive integer and consider the bipartite graph whose vertices are the -element subsets and the -element subsets of , and there is an edge be…
Sizes of flat maximal antichains of subsets
Jerrold R. Griggs, Thomas Kalinowski, Uwe Leck +2
This is the second of two papers investigating for which positive integers there exists a maximal antichain of size in the Boolean lattice (the power set of $[n]:=\{1…
Maximal antichains of subsets II: Constructions
Jerrold R. Griggs, Thomas Kalinowski, Uwe Leck +2
This is the second in a sequence of three papers investigating the question for which positive integers there exists a maximal antichain of size in the Boolean lattice $B_n…
The saturation spectrum for antichains of subsets
Jerrold R. Griggs, Thomas Kalinowski, Uwe Leck +2
Extending a classical theorem of Sperner, we characterize the integers such that there exists a maximal antichain of size in the Boolean lattice , that is, the power s…
Minimum Weight Flat Antichains of Subsets
Jerrold R. Griggs, Sven Hartmann, Thomas Kalinowski +2
Building on classical theorems of Sperner and Kruskal-Katona, we investigate antichains in the Boolean lattice of all subsets of , where $\…
