Item Characterization of Signed Symmetric Group in Inner Product Spaces(Adamawa State University, 2019) Usamot, I. F.; Rauf, K.; Bakare, G. N.; Ibrahim, G. R.This paper provides some characterizations of signed symmetric group (SSn) using the notion of orthogonality in inner product spaces. The concepts of ortho-stochastic and reflection were introduced on SSn and results were established with some examples.Item Fixed Point with Compatible Function on Semigroup of Linear Operator(Mathematical Association of Nigeria, 2019) Yussuff, A. A.; Ajisope, M. O.; Zubair, O. R.; Usamot, I. F.; Rauf, K.This paper consists of fixed point results on ω-order preserving partial contraction mapping as a weakly compatible function. Moreover, the results are established as semigroup of linear operator.Item On coefficient bounds of a subclass of univalent functions(Nigerian Mathematical Society, 2004) Opoola, T. O.; Babalola, Kunle Oladeji; Fadipe-Joseph, O. A.; Rauf, K.Let T(_n^α)(β) denote the class of functions f(z)=z+∑_(k=2)^∞▒〖a_k z^k 〗, univalent and analytic in the unit disk U={z∈ C:|z|<1} such that Re(D^n [〖f(z)〗^α])/z^α>β, z∈U,n∈{0}∪N,α>0,0≤β<1 and D^n is the salagean differential operator, in this paper, we establish some coefficient bounds for functions of the class T(_n^α)(β).Item On Idempotent of Some Orders-Preserving Full Contraction Mappings in Metric Spaces.(Department of Science Education, Federal University of Technology, Minna, Nigeria., 2017) Rauf, K.; Usamot, I. F.This paper discuss fixed point theorems on the idempotents of Order-Preserving Full Contraction Mappings E(OCTn) with property P and Q in metric spaces using Picard iterative scheme.Item On Sum Criterion for the Existence of Some Iterative methods.(Nigerian Association of Mathematical Physics., 2015) Rauf, K.; Wahab, O. T.; Omolehin, J. O.; Abdullahi, I.; Zubair, O. R.; Alata, S. M.; Usamot, I. F.; Sanusi, A. O.In this paper, we evoke an existence for two iterative methods of the system of linear equations. Our results agree with existing results and suggest a strong procedural condition for the convergence of the system of linear equations.
