The Hermitian elements of A play the role of generalized variables which, in principle, can be measured experimentally (hence the terminology “algebra of observables”). We now single out the class

It turns out that the combination of the spectrum property and Lorentz-invariance provides extra information about analyticity, in particular, it allows one to continue the functions analytically to a wider domain (called the extended t

Another essential feature of the .-matrix method is that it is well suited to the treatment of the dynamical equations of quantum field theory (see, for example, [Z1]).
