historyandoverviewofpolynomialp's Introduction

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

Abstract

The polynomial $\mathbf{P}^m_b(x)$ is a $2m+1$ degree polynomial in $(x,b) \in \mathbb{R}$ defined by an identity for odd-powers. The odd-power identity is derived applying certain interpolation approaches including systems of linear equations and recurrence relations. This manuscript provides a comprehensive historical survey of the milestones and evolution of the polynomial $\mathbf{P}^m_b(x)$ continuing with related works based on it. Notable results inside related works include the relation between ordinary and partial derivatives for odd-powers, finding the derivative of polynomials via double limit etc. Finally, the manuscript concludes with future research directions and activities.

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 terms 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

Please note that equation and references numbers in README may not match the actual in manuscript, so refer directly to PDF
