The second-order electron self-energy in hydrogen-like ions [PDF]

, 1999
A calculation of the simplest part of the second-order electron self-energy (loop after loop irreducible contribution) for hydrogen-like ions with nuclear charge numbers $3 \leq Z \leq 92$ is presented.

Rough I2 ${I}_{2}$-lacunary statistical convergence of double sequences

Journal of Inequalities and Applications, 2018
In this paper, we introduce and study the notion of rough I2 $\mathcal {I}_{2}$-lacunary statistical convergence of double sequences in normed linear spaces.

Ideal convergence and ideal Cauchy sequences in intuitionistic fuzzy metric spaces [PDF]

Mathematica Moravica, 2023
The present study introduces the concepts of ideal convergence (I-convergence), ideal Cauchy (I-Cauchy) sequences, I *-convergence, and I *-Cauchy sequences in intuitionistic fuzzy metric spaces.

Migration and Growth of Protoplanetary Embryos I: Convergence of Embryos in Protoplanetary Disks

, 2014
According to the core-accretion scenario, planets form in protostellar disks through the condensation of dust, coagulation of planetesimals, and emergence of protoplanetary embryos.

p-Regularity and p-Regular Modification in ⊤-Convergence Spaces

Mathematics, 2019
Fuzzy convergence spaces are extensions of convergence spaces. ⊤-convergence spaces are important fuzzy convergence spaces. In this paper, p-regularity (a relative regularity) in ⊤-convergence spaces is discussed by two equivalent approaches. In addition,

Weak and weak*I^K-convergence in normed spaces

Ratio Mathematica, 2023
The main object of this paper is to study the concept of weak $I^K$-convergence, a generalization of weak $I^*$-convergence of sequences in a normed space, introducing the idea of weak* $I^K$-convergence of sequences of functionals where $I,K$ are two ...

Estimation of System Parameters in Discrete Dynamical Systems from Time Series [PDF]

, 2004
We propose a simple method to estimate the parameters involved in discrete dynamical systems from time series. The method is based on the concept of controlling chaos by constant feedback.

On the Triple Lauricella–Horn–Karlsson q-Hypergeometric Functions

Axioms, 2020
The Horn–Karlsson approach to find convergence regions is applied to find convergence regions for triple q-hypergeometric functions. It turns out that the convergence regions are significantly increased in the q-case; just as for q-Appell and q ...
