Asymptotic Theorems and Averaging in Scalar Field Cosmology
Genly Leon, Aleksander Kozak, Claudio Michea
We present a hybrid study that combines a concise review of scalar-field cosmology with new analytic developments that integrate averaging reductions for oscillatory regimes with d…
Disformal transformations in a Palatini extension of Horndeski's gravity
Aleksander Kozak
In this paper, we extend Horndeski's theory into the Palatini approach, assuming that the metric tensor and the (symmetric) connection are a priori independent objects. We introduc…
Slow-Fast Evolution of Scalar Fields in Higher-Order Cosmological Gravity: Dynamics Inspired by the Pais--Uhlenbeck Oscillator
Manuel Gonzalez-Espinoza, Genly Leon, Yoelsy Leyva +3
We investigate the cosmological dynamics of scalar fields governed by higher-order gravity, with particular emphasis on models inspired by the Pais-Uhlenbeck oscillator--a prototyp…
Cosmological constraints of Palatini gravity
Débora Aguiar Gomes, Rebecca Briffa, Aleksander Kozak +3
In this study, we investigate a Palatini gravity model featuring a quadratic term correction, aligning it with the most recent expansion rate data, with a particular focus o…
Refining Bounds for Snyder and GUP Models through Seismic Wave Analysis
Aleksander Kozak, Anna Pachoł, Aneta Wojnar
This study investigates possibility of placing bounds on the parameters, arising from the non-commutative Snyder space-time model and Generalized Uncertainty Principle (GUP) approa…
