An application of a reduction method of R. Rado to the study of common transversals
Published online by Cambridge University Press: 26 February 2010
Extract
A reduction method due to R. Rado [7] yields an elegant proof of the Halls' theorems on transversals of a family of sets (see for example [4]). We use here this method to give simple new proofs of some basic theorems on common transversals of a pair of families of sets.
