摘要：

Single-particle, spin and charge excitations in strongly correlated electron systems are studied by using the numerically exact diagonalization method of small clusters. Particular emphases are placed on the Hubbard, extended Hubbard and t-J models in one-dimension. The excitations in the two-dimensional systems are discussed in the light of the results in the one-dimensional systems.
