We review different exact approaches to string theory. In the context of the Green–Schwarz
superstring, we discuss the action in curved backgrounds and its supercoset formulation …

A bstract Spin Matrix theory (SMT) limits provide a way to capture the dynamics of the
AdS/CFT correspondence near BPS bounds. On the string theory side, these limits result in …

A bstract In this work we present an alternative method to construct diverse non-relativistic
Chern-Simons supergravity theories in three spacetime dimensions. To this end, we apply …

A bstract We discuss the non-relativistic limit of string theory in AdS 5× S 5 for different
choices of embedding coordinates. We show that, if we consider Cartesian coordinates, the …

Inspired by Lie algebra expansion, we consider an extension of the algebra introduced in A.

A bstract We formulate the stringy nonrelativistic limits of the flat space and AdS 5× S 5 string
as coset models, based on the string Bargmann and extended string Newton-Hooke …

A bstract Spectral curve methods proved to be powerful techniques in the context of
relativistic integrable string theories, since they allow us to derive the semiclassical spectrum …

In this paper, we present two novel non-relativistic superalgebras which correspond to
supersymmetric extensions of the enlarged extended Bargmann algebra. The three …

We present a supersymmetric extension of the exotic Newtonian Chern–Simons gravity
theory in three spacetime dimensions. The underlying new non-relativistic superalgebra is …
