Essential renormalisation group

open access: yesSciPost Physics, 2022
We propose a novel scheme for the exact renormalisation group motivated by the desire of reducing the complexity of practical computations. The key idea is to specify renormalisation conditions for all inessential couplings, leaving us with the task ...

From celestial correlators to AdS, and back

open access: yesJournal of High Energy Physics, 2023
We present a general relation between celestial correlation functions in d-dimensions and Witten diagrams in (d + 1)-dimensional Euclidean anti-de Sitter (EAdS) space, to all orders in perturbation theory.

Partial-order reduction for general state exploring algorithms [PDF]

open access: yesInternational Journal on Software Tools for Technology Transfer, 2006
An important component of partial-order based reduction algorithms is the condition that prevents action ignoring, commonly known as the cycle proviso. In this paper we give a new version of this proviso that is applicable to a general search algorithm skeleton also known as the General State Expanding Algorithm (GSEA).

Partially Ordered Generalized Patterns and k -ary Words

open access: yesAnnals of Combinatorics, 2003
Recently, Kitaev [Ki2] introduced partially ordered generalized patterns (POGPs) in the symmetric group, which further generalize the generalized permutation patterns introduced by Babson and Steingr msson [BS]. A POGP p is a GP some of whose letters are incomparable.

Compact generation in partially ordered sets [PDF]

open access: yesJournal of the Australian Mathematical Society. Series A. Pure Mathematics and Statistics, 1987
AbstractSeveral “classical” results on algebraic complete lattices extend to algebraic posets and, more generally, to so called compactly generated posets; but, of course, there may arise difficulties in the absence of certain joins or meets. For example, the property of weak atomicity turns out to be valid in all Dedekind complete compactly generated ...

Generating interval and semi-order extensions of partially ordered sets

open access: yesCadernos do IME - Série Informática, 2022
This is an account of the collaboration and the research conduction by Prof. Jayme Luiz Szwarcfiter, during the development of the thesis of Aquiles Braga de Queiroz at COPPE/UFRJ, "Algoritmos para a Geração de Classes de Extensões de Conjuntos Parcialmente Ordenados", completed in 2005.

Interval Analysis and Calculus for Interval-Valued Functions of a Single Variable—Part II: Extremal Points, Convexity, Periodicity

open access: yesAxioms, 2019
We continue the presentation of new results in the calculus for interval-valued functions of a single real variable. We start here with the results presented in part I of this paper, namely, a general setting of partial orders in the space of compact ...

Scattering in black hole backgrounds and higher-spin amplitudes. Part II

open access: yesJournal of High Energy Physics, 2023
We continue to investigate correspondences between, on the one hand, scattering amplitudes for massive higher-spin particles and gravitons in appropriate quantum-to-classical limits, and on the other hand, classical gravitational interactions of spinning

Push-pull alkenes: Structure and -electron distribution [PDF]

open access: yesJournal of the Serbian Chemical Society, 2006
Push-pull alkenes are substituted alkenes with one or two electron-donating substituents on one end of C=C double bond and with one or two electron-accepting substituents at the other end.
