I am glad that you enjoyed the post.

I learned the technique of introducing a parameter to understand Dirichlet summation from Michael Trott several years ago. Neither he nor I are aware of any source that discusses and illustrates this method, but it was probably inspired by similar techniques that are used for regularization in quantum field theory.

]]>I really enjoyed your post! You state, on Dirichlet summation, that there is “another way to understand this answer is to introduce a parameter ε into the infinite sum and then apply …” and then you give some examples.

Could you point me to some literature that expands in detail on this method of understanding Dirichlet summation? I would like to study in more depth.

Best wishes, and thanks for helping to build Mathematica!
