Abstract We consider the dimensional reduction to two dimensions of certain gravitational theories in D ≥ 4 dimensions at the two-derivative level. It is known that the resulting field equations describe an integrable system in two dimensions which

Abstract The Riemann-Hilbert approach, in conjunction with the canonical Wiener-Hopf factorisation of certain matrix functions called monodromy matrices, enables one to obtain explicit solutions to the non-linear field equations of some gravitational

Abstract In this note, we explore holographic attributes of four-dimensional near-extremal Reissner-Nordstrom black hole solutions in ungauged N $$ \mathcal{N} $$ = 2 supergravity theories at the two-derivative level by recasting them as a specific f

Abstract We use continued fractions to perform a systematic and explicit characterization of the decays of two-centred dyonic black holes in 4D N $$ \mathcal{N} $$ = 4 heterotic ℤ N CHL models. Thereby we give a new exact solution for the problem o

Abstract We approach the problem of constructing an explicit holographic dictionary for the AdS2/CFT1 correspondence in the context of higher derivative gravitational actions in AdS2 space-times. These actions are obtained by an S 2 reduction of four

We use the exact degeneracy formula of single-centred $\frac14$ BPS dyonic black holes with unit torsion in 4D $N=4$ toroidally compactified heterotic string theory to improve on the existing formulation of the corresponding quantum entropy function

We consider four-dimensional dyonic single-center BPS black holes in the $N=2$ STU model of Sen and Vafa. By working in a region of moduli space where the real part of two of the three complex scalars $S, T, U$ are taken to be large, we evaluate the

We consider the Riemann-Hilbert factorization approach to the construction of Weyl metrics in four space-time dimensions. We present, for the first time, a rigorous proof of the remarkable fact that the canonical Wiener-Hopf factorization of a matrix
