History and overview of the polynomial $\mathbf{P}^m_b(x)$

Abstract

Polynomial $\mathbf{P}^m_b(x)$ is a $2m+1, \quad m\in\mathbb{N}$ degree polynomial in $(x,b) \in \mathbb{R}$, such that derived applying certain methods of interpolation, so that initially we reach the base case for $m=1$ generalizing it up to $m\in\mathbb{N}$ afterwards. In particular, the polynomial $\mathbf{P}^m_b(x)$ may be successfully applicable for polynomial interpolation and approximation approaches. This manuscript provides a comprehensive historical survey of the milestones and evolution of $\mathbf{P}^m_b(x)$ as well as related works such that based onto, for instance various polynomial identities, differential equations etc. In addition, future research directions are proposed and discussed.

Open research opportunities & other activities

Open research opportunities are described in the section "Future research" of current manuscript, still it is worth to duplicate them here

• Differential equation (2.1) can be expressed in terms of backward and central differentials, as well as its dynamic equation analogs [19]
• Definition (1.8) is closely related to discrete convolution, probably some new identities in term of discrete convolution may be found
• All kind of derivatives (forward, backward, central), including time scale ones can be expressed as double limit similarly to [20]
• Equation (1.8) approximates odd-power $2m+1$ in some neighborhood of fixed point a as it shown on graphs
• Validation and fixing grammar issues
