A theorem of Erdos asserts that every infinite subset of Euclidean n-space
R^n has a subset of the same cardinality having no repeated distances. This
theorem is generalized here as follows: If (R^n,E) is an algebraic hypergraph
that does not have an infinite, complete subset, then every infinite subset of
it has an independent subset of the same cardinality. 查看全文>>
