    Investigation of dark energy scenarios in f(Q) gravitation theory
    (World Scientific Publ Co Pte Ltd, 2024) Jalali, Samira; Aygun, Sezgin
    In order to solve the mystery of the accelerating and expanding universe model first, various dark energy candidates, such as Quintessence, Tachyon, k-essence, Phantom and DBI-essence, were investigated in detail in the f(Q) modified symmetric teleparallel gravitation theory for homogeneous and isotropic FRLW universe model. The f(Q) = aQ(n )+ b model is used to obtain solutions in f(Q) theory. Also, the physical behaviors of some cosmological parameters such as pressure and density were studied. Dark energy candidates were analyzed for different values of n with various graphs.

    Statistical Riesz and Nörlund convergence for sequences of fuzzy numbers
    (Amasya Üniversitesi, 2023) Arslan, Burak; Jalali, Samira; Enginoğlu, Serdar
    Nuray and Savaş proposed statistical convergence of fuzzy number sequences. Afterward, Tripathy and Baruah presented Riesz and Nörlund convergence for sequences of fuzzy numbers. This paper defines statistical Riesz and Nörlund convergence of fuzzy number sequences. It then shows that if a sequence of fuzzy numbers is convergent, then it is statistical Riesz/Nörlund convergent, but the converse is not always true. Finally, this paper discusses the need for further research.
