What is a (spatial) frame of reference in quantum mechanics?When we make a transformation e.g. in a H-atom from the proton frame of reference to the electron frame of reference. The whole point of QM is that the electron cannot be treated as a dot somewhere in space but that it has an associated wavefunction and only acquires a certain position when I make an appropriate measurement. So how can I transform to the electron frame of reference making the origin to be the position of the electron if I don't know it?
How many different triples f : A → S , g : B → S , h : C → S are there such that f, g, h are all injective, and f ( A ) = g ( B ) = h ( C )?In this Question we know that the | A | , | B | , | C | = m > 0 and set S has cardinality n > 0..Since the functions are one-to-one this means each domain maps a codomain and as all three sets (Domain) have same cardinality we can deduce that n C m possible codomain mapped by these functions.And because these functions are One-One, so each function can form n P m number of One-One function so according to me this leads me to n P m / n C m as number of different triples that can be formed.
