Abstract
The strong coupling limit of one-dimensional correlated systems is nontrivi
al, but simple in some sense. Here we demonstrate it, discussing the wave f
unctions for the 1D U --> +infinity Hubbard model, which are factorized as
a direct product of the charge part and the spin part and determining the o
ne-particle spectral functions explicitly.
