Well i am noobie to quantum physics so i matbe totally incorrect so please bear with me.
I had question how is position operator defined mathematically.
I was reading the momentum position commutator from http://ocw.mit.edu/courses/physics/...pring-2013/lecture-notes/MIT8_04S13_Lec05.pdf (page 2 of pdf)
They have used position operator = eigenvalue (ie position itself) times wavefunction http://ocw.mit.edu/courses/physics/...pring-2013/lecture-notes/MIT8_04S13_Lec05.pdf
But i doubt that the relation will be valid only for delta wavefunction (paralell to as momentum relation is valid in case of eix. I understood it as momentum is well defined in only that case so similarly position will be defined clearly in delta function only.)
So am i correct, also point pitfalls in my understandings
