In fact, you can pick any finite string of digits, toss out the terms containing those, and the result converges. With that set-up, let's talk about what all this means and how we can prove it.

The exterior boundary value problems of Laplace equation and linear elastic equations are considered. A series of approximate infinite boundary conditions are given. Then the original problem is ...

These techniques entail the explicit evaluation of finite and infinite series whose terms are trigonometric functions, thereby linking classical analysis with combinatorial and number theoretic ...
