A Note On Generalized Inequalities for the polar derivative of a polynomial
N. A. Rather, Danish Rashid Bhat, Tanveer Bhat
Let \( P(z) \) be a polynomial of degree \( n \) and . The polar derivative of \( P(z) \), denoted by \( D_αP(z) \) and is defined by $D_αP(z): = nP(z) + (α-z)P'(z…
A refinement of Cauchys theorem on the zeros of quaternion polynomial
Nisar Ahmad Rather, Danish Rashid Bhat, Tanveer Bhat
In this paper, we shall present an interesting and significant refinement of a classical result of Cauchy about the moduli of the zeros of a quaternionic polynomial. As an applicat…
