  We calculate the local correlation functions of charge and spin for the
one-chain and two-chain Hubbard model using the density matrix renormalization
group method and the recursion technique. Keeping only finite number of states
we get good accuracy for the low energy excitations. We study the charge and
spin gaps, bandwidths and weights of the spectra for various values of the
on-site Coulomb interaction U and the electron filling. In the low energy part,
the local correlation functions are different for the charge and spin. The
bandwidths are proportional to t for the charge and J for the spin,
respectively.
