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.
