A bstract We revisit the question of whether classical general relativity obeys, beyond the
linearised order, an analogue of the global U (1) electric-magnetic duality of Maxwell theory …

This article aims to study nonlocal Lagrangians with an infinite number of degrees of
freedom. We obtain an extension of Noether's theorem and Noether's identities for such …

This article aims to transform the infinite-order Lagrangian density for ghost-free infinite-
derivative linearized gravity into non-local form. To achieve it, we use the theory of …

This thesis aims to study nonlocal Lagrangians with a finite and an infinite number of
degrees of freedom. We obtain an extension of Noether's theorem and Noether's identities …

A bstract In this paper we study for the first time topological defects in the context of nonlocal
field theories in which Lagrangians contain infinite-order differential operators. In particular …
