Abstract:
We consider classical strings propagating in a background generated by
a sequence of TsT transformations. We describe a general procedure to derive the
Green-Schwarz action for strings. We show that the U(1) isometry variables of the
TsT-transformed background are related to the isometry variables of the initial background
in a universal way independent of the details of the background. This allows
us to prove that strings in the TsT-transformed background are described by the
Green-Schwarz action for strings in the initial background subject to twisted boundary
conditions. Our construction implies that a TsT transformation preserves integrability
properties of the string sigma model. We discuss in detail type IIB strings
propagating in the ?i-deformed AdS5?S5 space-time, find the twisted boundary conditions
for bosons and fermions, and use them to write down an explicit expression
for the monodromy matrix. We also discuss string zero modes whose dynamics is
governed by a fermionic generalization of the integrable Neumann model.
