A New Integral Transform for Solving Integral and Ordinary Differential Equations [PDF]

open access: yesMathematics and Computational Sciences
In this research paper, we introduce a new transform belonging to the class of Laplace transforms, called the Yasser-Jassim Transform (YJ Transform). We explore its properties and compare it to the classical Laplace transform.
