Multiplicative Harmonic <i>P</i> ‐Functions With Some Related Inequalities

This manuscript includes the investigation of the idea of a multiplicative harmonic P ‐function and construction of the Hermite–Hadamard inequality for such a sort of functions. We also establish several Hermite–Hadamard type inequalities in the setting of multiplicative calculus. Furthermore, we establish upper bounds for such a particular set of functions. Our conclusions are validated by presenting suitable examples with graphs. Through the analysis of this specific class of convex functions, our aim is to reveal novel mathematical viewpoints, characteristics, and relationships that can improve the advancement of more robust mathematical methodologies. Findings from this study contributes to the development of mathematical tools across a wide range of scientific disciplines.
