摘要
The recently released data of DESI DR2 favors a dynamical dark energy theory,with the equation of state crossing the cosmological constant boundary w=-1.In this paper,we briefly review quintom cosmology,especially the quintom bounce.We will give three examples of a quintom bounce and one example of a cyclic universe with quintom matter.
