Quantum invariants of 3-manifolds and Poincar\'{e} conjecture
  A new quantum gauge model is proposed. From this quantum gauge model we derive a quantum invariant of 3-manifolds. We show that this quantum invariant of 3-manifolds gives a classification of closed (orientable and connected) 3-manifolds.   From this classification we then prove the Poincar\'{e} conjecture.
