A generalized Neyman-Pearson lemma for sublinear expectations
Chuanfeng Sun, Shaolin Ji
In this paper, the Neyman-Pearson lemma for general sublinear expectations is studied. We weaken the assumptions for sublinear expectations in [1] and give a completely new method…
Forecasting cosmological constraints from age of high-z galaxies
C. A. P. Bengaly, M. A. Dantas, J. C. Carvalho +1
We perform Monte Carlo simulations based on current age estimates of high-z objects to forecast constraints on the equation of state (EoS) of the dark energy. In our analysis, we u…
Time and distance constraints on accelerating cosmological models
M. A. Dantas, J. S. Alcaniz, D. Mania +1
The absence of guidance from fundamental physics about the mechanism behind cosmic acceleration has given rise to a number of alternative cosmological scenarios. These are based ei…
Observational tests for Λ(t)CDM cosmology
C. Pigozzo, M. A. Dantas, S. Carneiro +1
We investigate the observational viability of a class of cosmological models in which the vacuum energy density decays linearly with the Hubble parameter, resulting in a production…
Current lookback time-redshift bounds on dark energy
M. A. Dantas, J. S. Alcaniz, N. Pires
We investigate observational constraints on dark energy models from lookback time (LT) estimates of 32 old passive galaxies distributed over the redshift interval $0.11 \leq z \leq…
Observational constraints on late-time Lambda(t) cosmology
S. Carneiro, M. A. Dantas, C. Pigozzo +1
The cosmological constant, i.e., the energy density stored in the true vacuum state of all existing fields in the Universe, is the simplest and the most natural possibility to desc…
