WebNov 1, 2024 · $\begingroup$ Look at the proof of GNS theorem and you will see that this is the correct point of view. Now I am too tired to write down an extended answer. $\endgroup$ – Valter Moretti. Oct 31, 2024 at 21:06 $\begingroup$ @ValterMoretti I believe I got the point by looking at the GNS construction. I posted one answer with my conclusion. WebIf we take a look at the GNS-condition for the representation and cyclic vector and interpret the Hilbert-Schmidt sesquilinear form, ... the only inspiration for constructing GNS-triplets is indeed the constructive proof of the GNS-theorem.
