$ U = e^{{ \frac{i \hbar t} {2m}} {\frac{d^2} {dx^2} }} $ I don't know what weak convergence is. I was reading R.Shankar's "Principle's of Quantum mechanics " & i encountered the above question. Can you suggest me the math i need to know in order to understand QM. Thankyou for the reply.

It's about the 'Propogator' of 1-D box ( -L/2 to +L/2) which is an exponential operator power series.

Hi, We know the convergence of a series but what does it mean to say that "an operator converges or diverges"?
