  • More on set-magic graphs

    • Authors: Ullas Thomas
      Pages: 93 - 97
      Abstract: This paper contains certain properties of set-magic graphs and obtained the set-magic number of certain classes of graphs. All spanning super graphs of a set-magic graph always set-magic and all cycles and Hamiltonian graphs are set-magic. Also set-magic number of any cycle of size 2n is always greater than n.

    • Authors: Yunhua Ye
      Pages: 98 - 102
      Abstract: This paper is concerned with the logarithmic convexity of the eigenfunction of the Hessian operator. It is proved that the logarithm of the eigenfunction of the Hessian operator is strictly convex in the ball.

  • Some types of fuzzy open sets in fuzzy topological groups

    • Authors: Mohamad Thigeel Hmod, Munir A. Al-khafaji, Taghreed Hur Majeed
      Pages: 103 - 107
      Abstract: The aim of this work is to introduce the definitions and study the concepts of fuzzy open (resp, fuzzy α- open, fuzzy semi- open, fuzzy pre- open, fuzzy regular- open, fuzzy b- open, fuzzy β- open) sets in fuzzy topological groups, and devote to study and discuss some of the basic concepts of some types of fuzzy continuous, fuzzy connected and fuzzy compact spaces in fuzzy topological groups with some theorems and Proposition are proved.

  • E-Bayesian analysis of the Gumbel type-ii distribution under type-ii
           censored scheme

    • Authors: Hesham Reyad, Soha Othman Ahmed
      Pages: 108 - 120
      Abstract: This paper seeks to focus on Bayesian and E-Bayesian estimation for the unknown shape parameter of the Gumbel type-II distribution based on type-II censored samples. These estimators are obtained under symmetric loss function [squared error loss (SELF))] and various asymmetric loss functions [LINEX loss function (LLF), Degroot loss function (DLF), Quadratic loss function (QLF) and minimum expected loss function (MELF)]. Comparisons between the E-Bayesian estimators with the associated Bayesian estimators are investigated through a simulation study.

           weıght 20 wıth level 12

    • Pages: 121 - 146
      Abstract: Williams and later Yao, Xia and Jin discovered explicit formulas for the coefficients of the Fourier series expansions of a class of eta quotients. Williams expressed all coefficients of 126 eta quotients in terms of σ(n),σ((n/2)),σ((n/3)) and σ((n/6)) and Yao, Xia and Jin, following the method of proof of Williams, expressed only even coefficients of 104 eta quotients in terms of σ₃(n),σ₃((n/2)),σ₃((n/3)) and σ₃((n/6)).Here, we will express the even Fourier coefficients of 570 eta quotients in terms of σ₁₉(n),σ₁₉((n/2)),σ₁₉((n/3)),σ₁₉((n/4)),σ₁₉((n/6)) and σ₁₉((n/(12))).
