Abstract
⺠I studied 2-dimensional Hubbard model on the honeycomb lattice. ⺠I used dynamical mean field theory for analysis of phase transition. ⺠The exact diagonalization method at zero temperature is used in this work. ⺠By increasing of the interaction the renormalized Fermi velocity factor decrease. ⺠The phase transition is the second order and critical on-site interaction is Uâ¼11.25.
