    On the Idempotent Elements of Semigroups of Injective Contraction Mappings
    (Development Universal Consortia, 2009-12-01) Kehinde, R., Makanjuola, S. O. and Adeshola, A. D.
    This paper studies the idempotents of the semigroups of injective contraction mappings(E(IONT_n) where n=1, 2. 3, 4. All the idempotent elements of partial 1 - 1 transformation semigroups are contraction mappings. Hence, |(E(IONT_n)|= 2^n = |(E(T_n)|.
