comment About the complex nature of the wave function?
But what are the differences between the sound waves and the wavefunction? Why the second must be complex, while the first also may interfere? And we may write the our wavefunction through sines and cosines, so the value $\psi^{T}\psi$ also refers to the invariant in this case.

comment Spin-statistics theorem proof details
@Qmechanic : this is a book published by my university. Unfortunately, this book is not in the public domain, and also it isn't written in English.
