Concordant mappings and the concordant-dissonant factorization of an arbitrary continuous function

P. J. Collins
1971 Proceedings of the American Mathematical Society  
The property of concordance (weaker than monotonicity) is introduced, and a characterization of concordant mappings using quotient spaces enables the derivation of a new factorization, the concordant-dissonant factorization of an arbitrary continuous function.
