A scalar field with a pole in its kinetic term is often used to study cosmological inflation;it can also play the role of dark energy,which is called the pole dark energy model.We propose a generalized model where the scalar field may have two or even multiple poles in the kinetic term,and we call it the multi-pole dark energy.We find that the poles can place some restrictions on the values of the original scalar field with a non-canonical kinetic term.After the transformation to the canonical form,we get a flat potential for the transformed scalar field even if the original field has a steep one.The late-time evolution of the universe is obtained explicitly for the two pole model,while dynamical analysis is performed for the multiple pole model.We find that it does have a stable attractor solution,which corresponds to the universe dominated by the potential of the scalar field.
