« Au Cœur Du Harem » Et Du Métissage Linguistique D’Elisa Chimenti En Italien : Comparaison Différentielle Et Décentrement Linguistique, Pierpaolo Amenta Jan 2025

« Au Cœur Du Harem » Et Du Métissage Linguistique D’Elisa Chimenti En Italien : Comparaison Différentielle Et Décentrement Linguistique, Pierpaolo Amenta

Al-Kīmiyā

This article examines the literary language of Elisa Chimenti (1883-1969), which is full of xenisms, linguistic loans, metaphors, and idioms that stem from a transcultural and heterolingual imaginary. Her novel Au cœur du harem (Éditions du Scorpion, 1958), translated into Italian in 2000 under the supervision of Emanuela Benini (Edizioni E/O), is a striking example. Drawing on a differential comparative approach (Heidmann, 2017), we look at these texts to reflect on Elisa Chimenti’s literary language and to examine the translational stakes of her work and its heterolingualism (Grutman, 1997; Suchet, 2014).

The Role Of Α-Inequalities In Examining The Singular Version Of The Big Bang Model, Samane Ijadi, S. Mansour Vaezpour, Mehdi Shabibi, Shahram Rezapour

Turkish Journal of Mathematics

In this article, by extending Friedmann's equation, we propose a singular fractional differential system for the Big Bang model. In this model, the rate of increase in the size of the universe tends to infinity at time near to zero and causes the emergence of a singular differential equation,which physically justifies the near-infinity energy of the universe in the near-zero volume of the universe in the early moments of the Big Bang. Then, we investigate this type of strong singular boundary value problem, by using $\alpha$-inequalities. In the sequel, some examples, describe the main results. Moreover, we present numerical and …
