SUMMARY
The discussion centers on the quantum mechanical operator Pr and its application to the function Y. The operator Pr is defined as Pr Y = -ih(bar) (1/r) d/dr (r Y). The user seeks to compute Pr^2 Y by applying the operator Pr twice, leading to the expression -h(bar)^2 (1/r) d/dr [Y(Y + r dY/dr)]. However, the user notes that their notes omit the first Y in the expression, which is confirmed to be unnecessary. The conclusion is that Pr^2 Y correctly represents the operation of Pr on Pr Y without the additional Y term.
