Dear Matti,

I am still stumbling on the first step of your proof in "1. The condition
guarateing unitarity." Could you explain proof of this section step by step
without omitting any steps?

Is this the only assumption in proving unitarity? Could you explain proof so
that a blind mathematician can understand it?
