Subclasses of Partial Contraction Mapping in Semigroup of Linear Operators

K. Rauf^*, A. Y. Akinyele, S. O. Makanjuola

Some properties of C0-Semigroup are investigated and are used to derive some characteristics of ω-Order Preserving and Reversing Partial Contraction Mapping where homo geneous, inhomogeneous and regularity of mild solution for analytic semigroups are engaged. Furthermore, the new sub classes performed exactly like semigroup of linear operators.

CARDINALITY AND IDEMPOTENCY OF SIGNED ORDER-PRESERVING TRANSFORMATION SEMIGROUPS

M. M. Mogbonju^*, S. O. Makanjuola, Adeniji A. O

Let SOn; SPOn and SIOn denotes the sets of signed full order - preserving, signed partial-order-preserving, and signed partial-one-one-order-preserving transformation semigroupsrespectively. Let be a transformation from Xn 􀀀! Z. This paper investigates and established the order and idempotency of the set of signed order-preserving transformation s...

Some Results on Properties of Alternating Semigroups

G. N. Bakare^*, S. O. Makanjuola

Let Cn be the symmetric inverse semigroup on Xn = {1,2,··· ,n}, Ac n be the alternating semigroups of Xn. In this paper, we discuss some combinatorial properties in An n. and obtained some triangles of numbers for it.
