Query: Critical Exponents without beta-Function   We point out that the recently developed strong-coupling theory enables us to
calculate the three main critical exponents nu, eta, omega, from the knowledge
of only the two renormalization constants Z_phi of wave function and Z_m of
mass. The renormalization constant of the coupling strength is superfluous, and
with it also the beta-function, the crucial quantity of the renormalization
group approach to critical phenomena.
