Abstract: In this paper, based on a new multiplication of fractional analytic functions, we find the fractional Fourier series expansions of two types of matrix fractional functions. Matrix fractional Euler’s formula and matrix fractional DeMoivre’s formula play important roles in this article. In fact, our results are generalizations of ordinary calculus results.    

Keywords: New multiplication, fractional analytic functions, fractional Fourier series expansions, matrix fractional functions, matrix fractional Euler’s formula, matrix fractional DeMoivre’s formula.

Abstract: Based on literature review and expert interviews, this study developed measurement tools to empirically demonstrate the positive and significant influence of mathematical culture on primary school students' interest in mathematics learning. An evaluation index system was established to measure the impact of mathematics culture on students' interest, and an evaluation model was constructed to assess the influence of mathematics culture on primary school students' interest in mathematics learning.

Keywords: Mathematics culture; Primary school students; Interest in mathematics learning; Evaluation model.

Abstract: The production of oil and natural gas from the earth core as a fuel to produce energy cause reduce in earth's mass that lead to change in some physical quantities, the speed of rotation around itself (around its axis) also around the sun. 

The angular momentum of the earth according to previous studies (literature review) will compare with that calculated in this study as it given in the table-1 which Show the earth's mass (M_e), oil mass (M_o) and natural gas mass (M_g), and table-2, Which show the angular momentum for earth (L_e) change in angular momentum due to change in earth's mass (ΔM_e) and the difference between earth's angular momentum and that after lost mass due to oil and natural gas mass. 

Keywords: Earth's mass, oil mass, natural gas mass and earth's angular momentum.

Abstract: An investigation of the structural, electrical, and optical properties of a monolayer of two-dimensional NbSe₂ is carried out with the assistance of the density functional theory. For the purpose of ensuring the structural and thermal stability of the monolayer, it is essential to ascertain the binding energy in addition to the phonon spectra. Through the use of first-principles simulations, we have investigated the electrical and optical properties of monolayers of NbSe₂ material. NbSe₂ monolayers have been shown to possess inherent properties that make them desirable for usage as two-dimensional materials in nanoelectronics applications. This discovery was made possible by the nature of the monolayers themselves. In addition, the optical properties of the NbSe₂ monolayers that were investigated for their two-dimensional applications are computed and described. These optical properties include the optical absorption coefficient, optical conductivity, reflectivity, and energy loss function.

Keywords: NbSe₂ monolayer, DFT, Band structure, Optical properties, metallic NbSe₂, Transition metal dichalcogenides.
