What does the expectation and deviation of an operator mean??
The way I understood it was every observable has a operator to it and the expectation of the observable uses the operator to calculate the deviation ...
for ex :: <p>=integral( (si)* momentum operator (si) ) dx ... so what does...

I started off with Zettilis Quantum Mechanics ... after being half way through D.Griffiths ... Now Zettilis precisely defines what a Hibert space is and it includes the Cauchy sequence and convergence of the same ... is...
the solution to the eigen function of the momentum operator is A*exp(ihx/p) where p is the eigen value which is satisfying the condition for the L2(a,b) space ... i.e., integral of the modulus of the complex number square which turns out to be A*2 ... which is less than infinity ... so y does it...
Hello,
I am going through the book Introduction to QM by D.Griffiths. In the third chapter the book says the eigen functions of the momentum operator do not belong to the Hilbert space ... But the only condition that a vector belongs to the Hilbert vector space is
that the integral...
