Annular Bounds for the Zeros of a Polynomial

Autor: Le Gao, N. K. Govil

Publikováno v: International Journal of Mathematics and Mathematical Sciences, Vol 2018 (2018)

The problem of obtaining the smallest possible region containing all the zeros of a polynomial has been attracting more and more attention recently, and in this paper, we obtain several results providing the annular regions that contain all the zeros

Modelling viscoelastic wave phenomenon by homogenisation of the poroelasticity equations

Autor: Q. Li, Fadil Santosa, K. Govil, B. Wheelock

Publikováno v: European Journal of Applied Mathematics. 32:846-864

Poroelastic effects have been of great interest in the seismic literature as they have been identified as a major cause of wave attenuation in heterogeneous porous media. The observed attenuation in the seismic wave can be explained in part by energy

On sharpening of inequalities for a class of polynomials satisfying p(z)≡znp(1/z)

Autor: N. K. Govil, Prasanna Kumar, Ritu Dhankhar

Publikováno v: Studia Scientiarum Mathematicarum Hungarica. 57:255-266

Let be a polynomial of degree n. Further, let and . Then according to the well-known Bernstein inequalities, we have and . It is an open problem to obtain inequalities analogous to these inequalities for the class of polynomials satisfying p(z) ≡ z
