Inferred from the community field; finer classification has not been reviewed.
Problem statement
Let denote the cardinality of the continuum. For ordinals and a cardinal , the 3-uniform ordinal Ramsey property is defined as follows: for any 2-coloring of all 3-element subsets of the ordinal type (where the coloring is given by a symmetric predicate on ordered triples of distinct elements), either there exists a subset of order type such that every 3-element subset of is colored red, or there exists a subset of cardinality such that every 3-element subset of is colored blue. Let denote the first infinite ordinal. Does the partition relation hold?
