Abstract
Elementary functions, Bessel functions, Legendre functions and many other special functions are included in the large family of mathematical functions known as generalized hypergeometric functions. A power series with coefficients that are rational functions of the index defines them. They are used in many disciplines, such as engineering, statistics and physics, because of their rich mathematical features and adaptability. The beauty and interdependence of mathematical ideas are demonstrated by the Generalized Hypergeometric Function. Researchers and practitioners from a wide range of disciplines find it to be an indispensable tool due to its unifying power, rich analytical features, and broad applications. Numerous unusual functions are included as particular examples of the generalized Hypergeometric function. Legendre polynomials, Bessel functions, the confluent Hypergeometric function, and numerous more noteworthy examples are also included. An order (q+1) linear homogeneous differential equation is satisfied by the generalized hypergeometric function. In many applications, but especially in mathematical physics, this differential equation is essential. It is possible to write the generalized hypergeometric function in terms of contour integrals, which offers different representations and makes it easier to evaluate some integrals. The generalized Hypergeometric function has a wealth of transformation formulas that allow one Hypergeometric function to be transformed into another with distinct parameters. These transformations are quite useful for examining relationships between various special functions and simplifying expressions.

Impact Statement
This study investigates the generalized hypergeometric function, a powerful and unifying mathematical tool that encompasses a wide range of special and elementary functions. By establishing novel representations and transformation identities, the work enhances understanding of the hypergeometric function’s role in solving complex differential equations, particularly those arising in physical models and computational mathematics. The ability to express numerous classical functions—like Legendre, Bessel, and trigonometric functions—as special cases of the generalized hypergeometric function provides a cohesive framework for theoretical and applied investigations. This contributes to both the simplification of mathematical modelling and the development of efficient computational methods.
