Srivastavaharimsri@math.uvic.caM. P. Chaudharydr.m.p.chaudhary@gmail.comSangeeta Chaudharysangeeta.ch289@gmail.comThe main object of this paper is to present some q-identities involving some of the theta functions of Jacobi and Ramanujan. These q-identities reveal certain relationships among three of the theta-type functions which arise from the celebrated Jacobi’s triple-product identity in a remarkably simple way. The results presented in this paper are motivated by some recent works by Chaudhary et al. (see [4] and [5]) and others (see, for example, [1] and [13]).2018-01-30T18:19:20+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://ejpam.com/index.php/ejpam/article/view/3085On ordered hypersemigroups with idempotent ideals, prime and weakly prime ideals2018-02-14T10:40:12+00:00Niovi Kehayopulunkehayop@math.uoa.grSome well known results on ordered semigroups are examined in case of ordered hypersemigroups. Following the paper in Semigroup Forum 44 (1992), 341--346, we prove the following: The ideals of an ordered hypergroupoid$H$ are idempotent if and only if for any two ideals $A$ and $B$ of $H$, we have $A\cap B=(A*B]$. Let now $H$ be an ordered hypersemigroup. Then, the ideals of $H$ are idempotent if and only if $H$ is semisimple. The ideals of $H$ are weakly prime if and only if they are idempotent and they form a chain. The ideals of $H$ are prime if and only if they form a chain and $H$ is intra-regular. The paper serves as an example to show how we pass from ordered semigroups to ordered hypersemigroups.2018-01-30T18:19:20+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://ejpam.com/index.php/ejpam/article/view/3182The Generalized Artin Primitive Root Conjecture2018-02-14T10:40:12+00:00N.

In this paper, we extend the concept of $\phi$-$2$-absorbing primary submodules to the context of $\phi$-$2$-absorbing semi-primary submodules. A proper submodule $N$ of $M$ is called a $\phi$-$2$-absorbing semi-primary submodule, if for each $m \in M$ and $a_{1}, a_{2}\in R$ with $a_{1}a_{2}m \in N - \phi(N)$, then $a_{1}a_{2}\in \sqrt{(N : M)}$ or $a_{1}m \in N$ or $a^{n}_{2}m\in N$, for some positive integer $n$. Those are extended from $2$-absorbing primary, weakly $2$-absorbing primary, almost $2$-absorbing primary, $\phi_{n}$-$2$-absorbing primary, $\omega$-$2$-absorbing primary and $\phi$-$2$-absorbing primary submodules, respectively. Some characterizations of $2$-absorbing semi-primary, $\phi_{n}$-$2$-absorbing semi-primary and $\phi$-$2$-absorbing semi-primary submodules are obtained. Moreover, we investigate relationships between $2$-absorbing semi-primary, $\phi_{n}$-$2$-absorbing semi-primary and $\phi$-primary submodules of modules over commutative rings. Finally, we obtain necessary and sufficient conditions of a $\phi$-$\phi$-$2$-absorbing semi-primary in order to be a $\phi$-$2$-absorbing semi-primary.2018-01-30T18:19:20+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://ejpam.com/index.php/ejpam/article/view/3196Some New Hermite-Hadamard-Fejer Type Inequlaties via k-Fractional Integrals Concerning Differentiable Generalized Relative Semi-(r; m, h1, h2)-Preinvex Mappings2018-02-14T10:40:12+00:00Miftar Ramosacajmiftar.ramosaco@gmail.comArtion Kashuriartionkashuri@gmail.comRozana Likorozanaliko86@gmail.comIn this article, we first presented a new identity concerning differentiable mappings defined on m-invex set via k-fractional integrals.

Al-Omaryradwan959@yahoo.comAn additive mapping F: R → R is called a generalized derivation on R if there exists a derivation d: R → R such that F(xy) = xF(y) + d(x)y holds for all x,y ∈ R. It is called a generalized (α,β)−derivation on R if there exists an (α,β)−derivation d: R → R such that the equation F(xy) = F(x)α(y)+β(x)d(y) holds for all x,y ∈ R. In the present paper, we investigate commutativity of a prime ring R, which satisﬁes certain diﬀerential identities on left ideals of R. Moreover some results on commutativity of rings with involutions that satisfy certain identities are proved.2018-01-30T18:19:21+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://ejpam.com/index.php/ejpam/article/view/3133Some Common Fixed Points of Six Mappings on G_b-metric Spaces Using (E.A) Property2018-02-14T10:40:12+00:00Zead Mustafazead@qu.edu.qaM.M.M.

LDA classifies new observations into one of the unknown groups and it is widely used in multivariate statistical analysis. The LDA mean and covariance matrix parameters are highly influenced by outliers. The DetMCD algorithm is highly robust and resistant to outliers and it is constructed to overcome the outlier problem. Moreover, the DetMCD algorithm is used to estimate location and scatter matrices. The DetMCD, FastMCD, FCH, and RFCH algorithms are applied to estimate misclassification probability using robust LDA. All the algorithms are expected to improve the LDA model for classification purposes in banks, such as bankruptcy and failures, and to distinguish between Islamic and conventional banks. The performances of the estimators are investigated through simulation and actual data.</p>2018-01-30T18:19:22+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://ejpam.com/index.php/ejpam/article/view/3131Between closed and Ig-closed sets2018-02-14T10:40:12+00:00Néstor Raúl Pachónnrpachonr@unal.edu.coThe concept of closed sets is a central object in general topology. In order to extend many of important properties of closed sets to a larger families, Norman Levine initiated the study of generalized closed sets. In this paper we introduce, via ideals, new generalizations of closed subsets, which are strong forms of the Ig-closed sets, called ρIg-closed sets and closed-I sets. We present some properties and applications of these new sets and compare the ρIg-closed sets and the closed-I sets with the g-closed sets introduced by Levine. We show that Iclosed and closed-I are independent concepts, as well as I∗-closed sets and closed-I concepts.2018-01-24T08:23:31+00:00Copyright (c) 2018 European Journal of Pure and Applied Mathematicshttps://ejpam.com/index.php/ejpam/article/view/2346Regularization of heptahedra using geometric element transformation method2018-02-14T10:40:12+00:00Buddhadev Palbuddha.pal@rediffmail.comSantu Deysantu.mathju@gmail.comArindam Bhattacharyyabhattachar1968@yahoo.co.inBy Geometric element transformation method (GETMe) always we get a new element.
