Abstract

    This paper introduces a novel double integral transform and highlights its theoretical and practical significance in solving complex mathematical problems. The fundamental definitions, key properties, and its relationships with existing integral transforms are systematically developed. The novelty of the proposed transform lies in its generalized structure, which extends the classical Mellin framework and provides a unified approach for handling a broader class of functions. Several applications are presented, including the derivation of Mellin transforms for elementary functions and the solution of partial and fractional differential equations. In addition, a comparative analysis with existing generalized Mellin transforms is carried out to demonstrate the advantages and efficiency of the proposed method. Finally, a comprehensive table of transforms for functions frequently arising in mathematics, physics, and engineering is provided to facilitate practical implementation.
