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.

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.

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).

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.
