In this research, we leverage various q -calculus identities to introduce the notion of q -Hermite-Appell polynomials involving three variables, elucidating their formalism. We delve into numerous properties and unveil novel findings regarding these q -Hermite-Appell polynomials, encompassing their generating function, series representation, summation equations, recurrence relations, q -differential formula, and operational principles. Our investigation sheds light on the intricate nature of these polynomials, elucidating their behavior and facilitating deeper understanding within the realm of q -calculus.
