We show analytically that, under certain assumptions, the periodic Anderson model and the Hubbard model
become equivalent within the dynamical mean field theory for quasiparticle weight 
.
A scaling relation is derived which is validated numerically using the numerical renormalization group
at zero temperature and quantum Monte Carlo simulations at finite temperatures. Our results show that the
f-electrons of the half-filled periodic Anderson model with nearest neighbor hybridization
get localized at a finite critical interaction strength Uc, also at zero temperature. This
transition is equivalent to the Mott-transition in the Hubbard model.
