Abstract
The exact dynamical equation for Efimov trimers in the short range limit of dimer resonances is derived via Yamaguchi separable potentials. This equation which overcomes the non-uniqueness problem of zero-range potentials, closely resembles one derived recently by Gogolin et al, with no further assumptions, and hence enjoys all the benefits of the latter results.
