Simplicity of AdS supergravity at one loop

open access: yesJournal of High Energy Physics, 2020
We demonstrate the simplicity of AdS 5 × S 5 IIB supergravity at one loop level, by studying non-planar holographic four-point correlators in Mellin space.

An Analytical Study of Diophantine Equations of Pythagorean Form: Causal Inferences on Hypothesized Relations between Quadratic and Non-quadratic Triples [PDF]

open access: yesAthens Journal of Education
In XVII century, presumably between 1637 and 1638, with a note in the margin of Diophantus’ “Arithmetica”, Pierre de Fermat stated that Diophantine equations of the Pythagorean form, x^n+y^n=z^n, have no integer solutions for n>2, and (x,y,z)>0.

On the dimensional indeterminacy of one-wave factor analysis under causal effects

open access: yesJournal of Causal Inference, 2023
It is shown, with two sets of indicators that separately load on two distinct factors, independent of one another conditional on the past, that if it is the case that at least one of the factors causally affects the other, then, in many settings, the ...

5d to 3d compactifications and discrete anomalies

open access: yesJournal of High Energy Physics, 2023
Much insight into the dynamics of quantum field theories can be gained by studying the relationship between field theories in different dimensions. An interesting observation is that when two theories are related by dimensional reduction on a compact ...

Quantum lattice algorithms: similarities and connections to some classic finite difference algorithms

open access: yesESAIM: Proceedings and Surveys, 2015
Quantum lattice algorithms originated with the Feynman checkerboard model for the one-dimensional Dirac equation. They offer discrete models of quantum mechanics in which the complex numbers representing wavefunction values on a ...

AN $L$ -FUNCTION-FREE PROOF OF VINOGRADOV’S THREE PRIMES THEOREM

open access: yesForum of Mathematics, Sigma, 2014
We give a new proof of Vinogradov’s three primes theorem, which asserts that all sufficiently large odd positive integers can be written as the sum of three primes. Existing proofs rely on the theory of

A face extralógica do Último Teorema de Fermat: um ensaio sobre a filosofia da prática matemática

open access: yesRevista de Educação Matemática, 2023
A Filosofia da Matemática durante muito tempo dedicou-se a aspectos ontológicos e epistemológicos para explicar os objetos da Matemática, área do conhecimento que costuma ser, tanto no ambiente escolar como no cotidiano, entendida como um reduto de ...

Toric geometry and the dual of c-extremization

open access: yesJournal of High Energy Physics, 2019
We consider D3-brane gauge theories at an arbitrary toric Calabi-Yau 3-fold cone singularity that are then further compactified on a Riemann surface Σ g , with an arbitrary partial topological twist for the global U(1) symmetries. This constitutes a rich,

Calibrating climate models using inverse methods: case studies with HadAM3, HadAM3P and HadCM3 [PDF]

open access: yesGeoscientific Model Development, 2017
Optimisation methods were successfully used to calibrate parameters in an atmospheric component of a climate model using two variants of the Gauss–Newton line-search algorithm: (1) a standard Gauss–Newton algorithm in which, in each iteration, all ...
