Description

After recalling the beta- and gamma deformations, we review briefly from a worldsheet perspective the lambda deformation and the general Yang-Baxter-type deformations. Focusing on the eta deformation, we discuss its worldsheet and target space properties. While this sigma model does not appear to define a critical string theory in the usual sense; we review the modified IIB equations of motion that the corresponding field configuration satisfies and their possible relation to the worldsheet theory.
