Abstract
The electron spectral function, the electron dispersion, and the electron d ensity of states of the two-dimensional t-J model on a triangular lattice a re studied within the self-consistent fermion-spin mean-field theory It is shown that there is a gap in the electron dispersions, and the global featu res of the electron spectral function is qualitatively similar to the resul t of the t-J model on a square lattice.
