Spiky strings, giant magnons, and β deformations

We study rigid string solutions rotating on the S-3 subspace of the beta-deformed AdS(5)xS(5) background found by Lunin and Maldacena. For particular values of the parameters of the solutions we find the known giant magnon and single spike strings. We present a single spike string solution on the deformed S-3 and find how the deformation affects the dispersion relation. The possible relation of this string solution to spin chains and the connection of the solutions on the undeformed S-3 to the sine-Gordon model are briefly discussed.
