. This work is concerned about the Cauchy problem for the following generalized KdV- Burgers equation where L p is a dissipative multiplier operator. Using Besov-Bourgain Spaces, we establish a bilinear estimate and following the framework developed in [14] we prove sharp local and global well-posedness in the Sobolev spaces H − p / 2 ( IR ) and ill-posedness in H s ( IR ) when s < − p / 2, both when p (cid:2) 2. Also, we prove C 2 -ill-posedness in H s ( IR ) , for s < 3 / 2 − p / 4 and 0 (cid:3) p (cid:3) 2.
