Representations and Dynamics book
In this chapter we shall examine different ways in which one can represent the evolution of a quantum state. While mathematically different, the various representations are equivalent in that, at the end of the day, one obtains the same physical prediction. This is good because physics and physical measurements should not depend upon how one chooses to represent the quantum state. Depending upon the problem at hand, each representation has its unique advantages and disadvantages.
