We give an introductory review of gauge/gravity duality, and associated ideas of holography,
emphasising the conceptual aspects. The opening sections gather the ingredients, viz. anti …

This paper has three main aims: first, to give a pedagogical introduction to Noether's two
theorems and their implications for energy conservation in general relativity, which was a …

This paper investigates the significance of T-duality in string theory: the indistinguishability
with respect to all observables, of models attributing radically different radii to space—larger …

A “duality” is a formal mapping between the spaces of solutions of two empirically equivalent
theories. In recent times, dualities have been found to be pervasive in string theory and …

In this paper I develop a framework for relating dualities and emergence: two notions that
are close to each other but also exclude one another. I adopt the conception of duality as …

The main aim of this paper is to make a remark about the relation between (i) dualities
between theories, as' duality is understood in physics and (ii) equivalence of theories, as …

A possible way out of the conundrum of quantum gravity is the proposal that general
relativity (GR) emerges from an underlying microscopic description. Despite recent interest …

In this paper we present a schema for describing dualities between physical theories (Sects.
2 and 3), and illustrate it in detail with the example of bosonization: a boson-fermion duality …

In their programmatic special issue on the emergence of spacetime in quantum theories of
gravity, Huggett and Wuthrich (2013, p. 284) write that the program of 'interpreting a theory …

It is often claimed that Einstein's magnum opus—-his 1915 theory of General Relativity—-is
distinguished from other theories of space and time in virtue of its background …
