Relative polars in ordered sets Radomír Halaš (2000) Czechoslovak Mathematical Journal Similarity: In the paper, the notion of relative polarity in ordered sets is introduced and the lattices of R -polars are studied. Connections between R -polars and prime ideals, especially in distributive sets, are found.
