A bstract We derive the part of the Lagrangian for the sigma model on the η-deformed AdS
5× S 5 space which is quadratic in fermions and has the full dependence on bosons. We …

A bstract Yang-Baxter string sigma-models provide a systematic way to deform coset
geometries, such as AdS p× S p, while retaining the σ-model integrability. It has been shown …

A bstract In this paper, based on simple analytic techniques, we explore the integrability
conditions for classical stringy configurations defined over η as well as λ-deformed …

The sigma model of closed strings spinning in the η deformation of AdS 5× S 5 leads to an
integrable deformation of the one-dimensional Neumann-Rosochatius mechanical system …

In this PhD thesis we review some aspects of integrable models related to string
backgrounds or their deformations. In the first part we develop methods to obtain exact …

A bstract We study rigidly rotating strings in ϰ-deformed AdS background. We probe this
classically integrable background with 'spiky'strings and analyze the string profiles in the …

A bstract We present a detailed study of the pulsating string solutions in AdS 3× S 3
supported by both RR and NS-NS fluxes. This background has recently been proved to be …

A bstract In this paper, we investigate pulsating string solutions within the context of two
parameter χ-deformed\(\mathcal {R}\)× S 2 background. We derive the energy and …

We study pulsating strings both on a single stack of NS5-branes and two orthogonal stacks
of NS5-branes (the so called I-brane) by using the Polyakov form of the fundamental string …

A bstract The so called one-parameter (often called ϰ) deformed AdS string sigma models
have attracted a lot of attention lately in the study of integrability in string theory. We …
