Fractional and noncommutative spacetimes
, 2011 We establish a mapping between fractional and noncommutative spacetimes in configuration space. Depending on the scale at which the relation is considered, there arise two possibilities.

Cyclic Universe and Infinite Past [PDF]
, 2007 We address two questions about the past for infinitely cyclic cosmology. The first is whether it can contain an infinite length null geodesic into the past in view of the Borde-Guth-Vilenkin (BGV) "no-go" theorem, The second is whether, given that a ...

On the max-algebraic core of a nonnegative matrix [PDF]
, 2013 The max-algebraic core of a nonnegative matrix is the intersection of column spans of all max-algebraic matrix powers. Here we investigate the action of a matrix on its core.

Forecasting Inflation Based on Hybrid Integration of the Riemann Zeta Function and the FPAS Model (FPAS + ζ): Cyclical Flexibility, Socio-Economic Challenges and Shocks, and Comparative Analysis of Models [PDF]
SocioEconomic ChallengesInflation forecasting is one of the main socio-economic challenges in modern macroeconomic modeling, especially when cyclical, structural, and shock factors act simultaneously in the system. Traditional forecasting systems, such as Forecasting and Policy

Local Weyl modules and cyclicity of tensor products for Yangians of $G_2$
, 2015 Let $\mathfrak{g}$ be the exceptional complex simple Lie algebra of type $G_2$. We provide a concrete cyclicity condition for the tensor product of fundamental representations of the Yangian $Y(\mathfrak{g})$.

Cyclic Variation of Residual (CO2 + H2O) and Total Pressure in Conifer Stem and Woody Root Tree Rings [PDF]
Журнал Сибирского федерального университета: Серия Биология, 2018 Tree-ring chronologies of stem discs and core samples have been widely used to reconstruct the climatic conditions of tree growth. However, insufficient attention has been given to the fact that root and stem wood accumulate biogenic gases, whose ...

On the cyclicity of the rational points group of abelian varieties over finite fields
, 2018 We propose a simple criterion to know if an abelian variety $A$ defined over a finite field $\mathbb{F}_q$ is cyclic, i.e., it has a cyclic group of rational points; this criterion is based on the endomorphism ring End$_{\mathbb{F}_q}(A)$.

Fuzzy spaces from tensor models, cyclicity condition, and n-ary algebras
, 2012 The rank-three tensor models, which have a rank-three tensor as their only dynamical variable, may be interpreted as models of dynamical fuzzy spaces.

Orbital frequencies in the carbonate sedimentary record: distorted by diagenesis? [PDF]
, 2004 The most important archive of Earth’s climate change through geologic history is the sedimentary rock record. Rhythmic sedimentary alternations are usually interpreted as a consequence of periodic variations in the orbital parameters of the Earth.
