we consider the spacetime with a zero-point length as proposed in [19,20,21]. Having a minimum length or minimum resolvable distance in the spacetime of the order of Planck length () is also another ubiquitous feature among many different approaches...
The rationale is to convert the integral equation at hand to a Fredholm second-kind equation by suitably inverting the most singular part of the integral operator. Of course, based on the problem at hand, the integral operator to be inverted can be conveniently identified with the static part,...
