Using function machines to solve equations Function machines can be used to solve equations by reversing, or finding the inverse of the steps.

This most significant parametric function is not always easy to find, however, because it may not manifest itself in simple or "obvious" functions. A general solution to this problem is presented ...

Linear functional differential equations of mixed type are typically ill-posed, i.e., there exists, in general, no solution to a given initial condition. We prove that Fredholm properties of these ...
