Combinatorial characterization of \(\Pi_1^1\)-indescribability in \(P_\kappa\lambda\)
The author investigates \(\Pi^1_1\)-indescribability of subsets of \(P_\kappa\lambda\). He describes a combinatorial property which is equivalent to \(\Pi^1_1\)-indescribability and does not depend on the cofinality of \(\lambda\). Further on he studies the relations between \(\Pi^1_1\)-indescribability and supercompactness.
