For each symmetry operation R acting on a physical system,there is a corresponding unitary transformation U(R).(adsbygoogle = window.adsbygoogle || []).push({});

But what is the priciple for such relation?

an example is that : for a continuous symmetry ,we can choose R infinitesimally close to the identity ,R=I+eT ,and the U is close to I,

U=I-ieQ+O(e^2)

another example is that R=(I+Tx/N)^N then U(R)=(I+iQx/N)^N

but i still can not figure out the relation between R and U(R)
