Furthermore the obtained Laplacian operator was used to obtain the generalized quantum mechanical wave equation for particles within this field. The Laplacian operator obtained in this work reduces to the well known Laplacian operator in the &nbsp;&nbsp;&nbsp;limit of <img src="/public/site/images/sciencedomain/Capture_11.PNG">, and it contained post Euclid or pure Riemannian correction terms of all orders of&nbsp;<img src="/public/site/images/sciencedomain/Capture_2.PNG"> . Also the generalized quantum mechanical wave equation obtained, in the limit of&nbsp;<img src="/public/site/images/sciencedomain/Capture_12.PNG">reduces to the well known Schrodinger mechanical wave equation, and in the limit of <img src="/public/site/images/sciencedomain/Capture_21.PNG">contained additional correction terms not found in the well known Schrodinger wave equation. Hence the results in this work satisfy the Principle of Equivalence in Physics.</p> A. U. Maisalatee W. L. Lumbi I. I. Ewa M. Mohammed Y. K.
