D-instantons in Type IIA string theory on Calabi-Yau threefolds
Journal of High Energy Physics, 2021 Type IIA string theory compactified on a Calabi-Yau threefold has a hypermultiplet moduli space whose metric is known to receive non-perturbative corrections from Euclidean D2-branes wrapped on 3-cycles.

Blackfolds, Plane Waves and Minimal Surfaces [PDF]
, 2015 Minimal surfaces in Euclidean space provide examples of possible non-compact horizon geometries and topologies in asymptotically flat space-time. On the other hand, the existence of limiting surfaces in the space-time provides a simple mechanism for ...

AM: Art + Media, 2016 The first objective of this work is to establish a parallel between the ordinary language philosophy of Ludwig Wittgenstein as well as the philosophy of Stanley Cavell and poststructuralism and its theories through their apprehension of vision and seeing

Nature, 1943 THE philosopher Kant declared that Euclidean geometry was inherent in the human mind and expressed the truth about space. We now recognize that non-Euclidean geometry is equally valid as an abstract system, and that one particular form (due to Riemann) has more claim than Euclidean geometry to represent the properties of physical space.

Non-representable hyperbolic matroids [PDF]
Discrete Mathematics & Theoretical Computer Science, 2020 The generalized Lax conjecture asserts that each hyperbolicity cone is a linear slice of the cone of positive semidefinite matrices. Hyperbolic polynomials give rise to a class of (hyperbolic) matroids which properly contains the class of matroids ...

Supersymmetric indices factorize
Journal of High Energy Physics, 2023 The extent to which quantum mechanical features of black holes can be understood from the Euclidean gravity path integral has recently received significant attention. In this paper, we examine this question for the calculation of the supersymmetric index.

From numbers to forms. The digital turn in morphogenic processes
Agathón, 2022 The digital turn, or specifically the second Digital Turn, was at disposal of the architectural and urban project sophisticated morphogenic tools. These tools have been used mainly to create new forms with non-Euclidean geometries and their integration ...

3+1 spinfoam model of quantum gravity with spacelike and timelike components [PDF]
, 2000 We present a spinfoam formulation of Lorentzian quantum General Relativity. The theory is based on a simple generalization of an Euclidean model defined in terms of a field theory over a group.
