In this paper, we introduce a new comprehensive subclass ?B(?,?,?) of meromorphic bi-univalent functions in the open unit disk U. We also find upper bounds for initial Taylor-Maclaurin coefficients |b0|, |b1| and |b2| subclass. Moreover, obtain estimates general |bn|(n?1) by making use Faber polynomial expansion method. The results presented paper would generalize improve several recent works o...

By using the generalization of neutrosophic q-Poisson distribution series, we introduce a new subclass analytic and bi-univalent functions defined in open unit disk. We then apply q-Gegenbauer polynomials to investigate estimates for Taylor coefficients Fekete–Szegö type inequalities belonging this subclass. In addition, consider several corollaries consequences results presented paper. The is ...

Cucumber (Cucumis sativus L.) is threatened by substantial yield losses due to the south root-knot nematode (Meloidogyne incognita). However, understanding of the molecular mechanisms underlying the process of nematode infection is still limited. In this study, we found that M. incognita infection affected the structure of cells in cucumber roots and treatment of the cytoskeleton inhibitor (cyt...

In the real world there are many applications that find Bell distribution to be a useful and relevant model. One of these is normal distribution. this paper, we develop new subclass analytic bi-univalent functions by making use as building block. These involve Gegenbauer polynomials, them establish our subclass. study, solve Fekete–Szegö functional problem analyse various different estimates Ma...

we consider the class of polynomial differential equation x&= , 2(,)(,)(,)nnmnmpxypxypxy++++2(,)(,)(,)nnmnmyqxyqxyqxy++&=++. for where and are homogeneous polynomials of degree i. inside this class of polynomial differential equation we consider a subclass of darboux integrable systems. moreover, under additional conditions we proved such darboux integrable systems can have at most 1 limit cycle.

Abstract We formulate a generalization of Riesz-type criteria in the setting L -functions belonging to Selberg class. obtain criterion which is sufficient for grand Riemann hypothesis (GRH) satisfying axioms class without imposing Ramanujan on their coefficients. also construct subclass and prove necessary GRH this subclass. Identities Ramanujan–Hardy–Littlewood type are established setting, sp...

Making use of an extended fractional differintegral operator (introduced recently by Patel and Mishra), we introduce a new subclass of multivalent analytic functions and investigate certain interesting properties of the subclass.
