Inverse Differential Operators in Time and Space
《Journal of Applied Mathematics and Physics》2023年第12期3789-3799,共11页Edwin Eugene Klingman 
When one function is defined as a differential operation on another function, it’s often desirable to invert the definition, to effectively “undo” the differentiation. A Green’s function approach is often used to ...
