http://system.lm-ns.org/index.php/lm-ns/article/view/1429
We consider the existence of asymptotically periodic solutions of a gross-substitute discrete system, which appear as tatonnement processes of mathematical economic models, by using uniformly stable and the properties of a gross-substitute discrete system.Kaori Saito2019-10-082019-10-0839Relationship between the left-right Jeribi essential spectra and the left-right Weyl essential spectra of closed densely de ned linear operators
http://system.lm-ns.org/index.php/lm-ns/article/view/1443
In the present paper, we introduce and study the notion of the left-right Jeribi essential spectra, and we characterize the left-right Weyl essential spectra of closed densely de ned linear operators. Furthermore, we apply the obtained results to study the transport equation.Aymen AmmarBilel BoukettayaAref Jeribi2019-04-092019-04-0939Determinant for bi-univalent of pseudo starlikeness for certain class of analytic univalent functions
http://system.lm-ns.org/index.php/lm-ns/article/view/1440
This paper introduces and investigates the polynomials whose coefficients are bi-univalent of generalized distribution. We employed method of convolution via generalized polylogarithm and Sigmoid function to obtain first few coefficients of the defined subclasses. Furthermore, second and third Hankel determinant for the class defined were established. Consequences of various choices of parameter were discussed which further establish geometric properties of the generalized distribution associated with bi-univalent functions.Ibrahim Tunji AwolereAbiodun Tinuoye Oladipo2019-11-092019-11-0939A CLASS OF MEROMORPHIC FUNCTIONS WITH POSITIVE COEFFICIENTS INVOLVING POLYLOGARITHM FUNCTIONS
http://system.lm-ns.org/index.php/lm-ns/article/view/1432
In this paper, we introduce and study a new subclass of meromorphic functions with positive coefficients involving the Polylogaritham function defined by a new operator~ $\mathfrak{D}_c f(z)$~ and obtain coefficient estimates, growth and distortion theorem, radius of convexity, integral transforms,convex linear combinations,convolution properties and~ $\delta-$neighborhoods for the class~ $\sigma_{c,p}(\alpha).$B.

http://system.lm-ns.org/index.php/lm-ns/article/view/1428
The notion and some properties of (strongly) B-rings, in a natural way, are extended to (strongly) B- and (strongly) BJ -semirings which is somewhat similar to the notion of rings having stable range 2. Results are given showing the connection between several types of semirings whose nite sequences satisfy some stability condition, some involving the Jacobson k-radical of the semiring R. Besides some examples and other results, it is shown that R[x], the semiring of polynomials over a semiring R, is not a B-semiring (consequently, not a strongly B-semiring) when R is a zerosumfree semiring.Amir Massoud Rahimi2020-04-072020-04-0739ON Lambda PSEUDO BI-STARLIKE FUNCTIONS RELATED (p; q)-LUCAS POLYNOMIAL
http://system.lm-ns.org/index.php/lm-ns/article/view/1438
In this paper we introduce a new class L(; x) of Lambda-pseudo bi-starlike functions through the (p; q)-Lucas polynomials and determine the bounds for |a2| and |a3| where a2, a3 are the initial Taylor coecients of f 2 L(; x): Furthermore, we estimate the Fekete-Szego functional for f 2 L(; x): We pointed out several new or known consequences of our result.Gangadharan MurugusundaramoorthySibel Yalçın2019-12-172019-12-1739A memorial tribute to Professor Constantin Corduneanu, the outstanding matematician
