In the next, we define $M(T)$ as the smallest constant such that $dist(\lambda,\sigma(T))\leq M(T) R_\lambda (T),$ for all $\lambda \in \partial W(T)$, where $R_\lambda (T)$, the radius curvature at the point $\lambda$, is defined. Also, we investigate for non-convexoid $T$, $M(T)=\sup\frac{dist(\lambda,\sigma(T))}{R_{\lambda}(T)}$, where the supremum on the right-hand side is taken along all points $\lambda\in \partial W(T)$ with finite non-zero curvature.

Network designers have taken a big step forward in the development of networks, and the solution to achieve this progress in networks is the use of software-based networks. In recent years, despite much research in the field of this type of network, there is still a need for optimizations in this area. One of the challenges that currently needs work and development is the issue of fault tolerance and failure in these networks. In this paper, various failure tolerance methods in software-defined networks are introduced.https://ijnaa.semnan.ac.ir/article_9028_a3b555ea1eb75a92e2b3dbd46a22f2d5.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682216520250501On the action of Toeplits operators into new BMOA type spaces in the unit disk7785877110.22075/ijnaa.2024.33014.4917ENRomiShamoyanSaratov National Research State University named after N.

It is proven that VS is more useful to solve many real life problems having uncertainties. Fuzzy graphs (FGs) are efficient mathematical models for analyzing many problems of daily life. One of the most widely used types of FG is vague incidence graph (VIG). VIGs play an important role in various fields such as computer science, pcychology, medicine, and political sciences and are used to find effective people in an organization or social institution. They can be used to describe the problems which cannot be handled through FGs and VGs. So, in this paper, specific ideas analogous to vague cut vertices and vague bridges in VGs, vague incidence cut-vertices, and vague incidence bridges are explored. The notion of vague incidence gain and vague incidence less for vague incidence paths and pairs of vertices is also initiated.https://ijnaa.semnan.ac.ir/article_8773_ee723e12e366697674c6a66fe1ff0561.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682216520250501Investigating the path analysis of smart marketing strategy on improving the marketing performance of Saderat Khorasan Razavi Bank119128902610.22075/ijnaa.2022.27703.3691ENMahdiehIravaniDepartment of Business Management, Central Tehran Branch, Islamic Azad University, Tehran, IranSoheilSarmad SaidyDepartment of Business Management, Central Tehran Branch, Islamic Azad University, Tehran, IranBehrouzGhasemiDepartment of Business Management, Central Tehran Branch, Islamic Azad University, Tehran, IranJournal Article20220507One of the reasons for the poor performance of some bank branches is their poor marketing. On the one hand, there is no specific tool to measure the development of marketing activities in the branches, especially the issues that are under the control of the branches themselves; Therefore, a concept called "smart marketing" has been defined to check to what extent the branches are in front of the smart environment and with what quality they carry out marketing measures according to their authority. Therefore, the purpose of the current research was to analyze the path of intelligent marketing strategy to improve the marketing performance of Saderat Khorasan Razavi Bank. According to the research process, the research method is a descriptive survey. The statistical population is all managers, assistants and marketing experts of Bank Saderat Khorasan Razavi in the number of 567 people, of which 229 people were selected by simple random method. The data collection tool was a researcher-made questionnaire, and the data were analyzed using the structural equation modelling method and Lisrel software, and the results showed that there was a positive and significant effect on all research variables.https://ijnaa.semnan.ac.ir/article_9026_a4d02616504fd2c13539b0f5179ef7ea.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682216520250501Fixed point theorems for weakly contractive mapping on generalized asymmetric metric spaces129142877510.22075/ijnaa.2022.26939.3455ENMohamedRossafiLaSMA Laboratory Department of Mathematics, Faculty of Sciences Dhar El Mahraz, University Sidi Mohamed Ben Abdellah, P.

Accounting and auditing as knowledge, experience and skills that are always on the path of growth, from the two perspectives of knowledge and professionalism, are always intertwined in various dimensions with the surrounding environment and society of the organizations and companies and on the path of evolution, progress, construction and interaction are in communication and interaction with many actors and networks. The theory of actors pays attention to the relationship between variables. The existing communication and recognition of the role of each actor in an organizational environment, regarding the functions of the information system, can contribute to the extensive evolution of accounting from two perspectives of knowledge and profession. The Actor-network theory is one of the theories of sociology. Auditing every organization always tries to operate efficiently, effectively, and with the lowest cost, using all facilities for economic effectiveness and helping the management provide timely reporting for strategic decisions. The independent evaluation of managers' performance is done through these internal audit groups. The present research is correlational and scientific, and it was carried out using questionnaires, distributed among 250 accountants and auditors of Iranian public and private auditing institutions and the stock exchange market, as well as using the SPSS Software. Based on this, according to the practical aspects of the research and as a distinguishing feature from other conducted research, considering its innovative aspect, the effect of the actors-network and its constituent parts is explained, and its impact is investigated in improving the situation and strategic decisions.https://ijnaa.semnan.ac.ir/article_9030_84ecb042b9cb82bc2a66f85551a26300.pdfSemnan UniversityInternational Journal of Nonlinear Analysis and Applications2008-682216520250501A new class of generalized convex functions and mathematical programming153164878110.22075/ijnaa.2024.32577.4848ENNajeebAbdulaleemFaculty of Mathematics and Computer Science, University of Lodz, Banacha 22, 90-238 Lodz, PolandDepartment of Mathematics, Mahrah University, Al-Mahrah, YemenDepartment of Mathematics, Hadhramout University, Al-Mahrah, YemenSolomonLalmalsawmaDepartment of Mathematics, National Institute of Technology, Chaltlang, Aizawl, 796012, Mizoram, IndiaVinaySinghDepartment of Mathematics, National Institute of Technology, Chaltlang, Aizawl, 796012, Mizoram, IndiaJournal Article20231206In this paper, a new class of nonconvex optimization problem is considered, namely $(h,\varphi)$-$(b,F,\rho)$-convexity is defined for $(h,\varphi)$-differentiable mathematical programming problem.
