A bstract We further develop the string 1/c 2 expansion of closed bosonic string theory,
where c is the speed of light. The expansion will be performed up to and including the next …

A bstract It is well known that one can take an infinite speed of light limit that gives rise to non-
relativistic strings with a relativistic worldsheet sigma model but with a non-relativistic target …

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 We expand the relativistic open bosonic string in powers of 1/c 2 where c is the
speed of light. We perform this expansion to next-to-leading order in 1/c 2 and relate our …

We show that a novel holographic correspondence appears after taking a suitable stringy
nonrelativistic limit of the AdS 5/CFT 4 duality. This correspondence relates string theory in …

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 …

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 …

We construct a new type of holographic correspondence between non-relativistic string
theory in String Newton-Cartan AdS $ _5\times $ S $^ 5$ and Galilean Electrodynamics …

We find the connection between relativistic and nonrelativistic string vacua in AdS 5× S 5 in
terms of a free parameter c flow. First, we show that the famous relativistic BMN vacuum …

A bstract There is a surge of research devoted to the formalism and physical manifestations
of non-Lorentzian kinematical symmetries, which focuses especially on the ones associated …
