We analyze the stability conditions to better understand the behavior of the system when we include or exclude the immigration effect in the discrete system. Furthermore, we demonstrate that the discrete system undergoes supercritical Neimark–Sacker bifurcation when the bifurcation parameter passes through a critical value. We also study the state feedback chaos control strategy for the discrete system and we obtain the triangular region restricted by the lines that contain stable eigenvalues. Moreover, we illustrate phase portraits, maximum Lyapunov exponents, and bifurcation diagrams for the discrete system. We present the numerical simulations to validate the theoretical findings. Finally, with the advantage of the nonstandard finite difference discretization method, we eliminate the flip bifurcation that occurs when Euler discretization is used.","PeriodicalId":15034,"journal":{"name":"Journal of Applied Mathematics and Computing","volume":"188 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The time-fractional derivative is approximated by Caputo’s time derivative. The space derivative is approximated by the collocation method based on improvised quintic B-spline functions. It is shown that the proposed algorithm is unconditionally stable. Through rigorous convergence analysis, the method is shown ((2-beta )) order convergent in time and almost sixth-order convergent in space direction. It is also shown that the theoretical rate of convergence is the same as that acquired experimentally. To confirm the theoretical results and to test the efficiency and robustness, the method is tested on three problems. The main contribution of the developed algorithm is that the order of convergence and numerical results obtained are better than the existing methods, like the sextic B-spline collocation method (Roul and Goura in Appl Math Comput 366:124727, 2020), the quintic B-spline method (Siddiqi and Arshed in Int J Comput Math 92(7):1496–1518, 2015), and the quintic spline method (Tariq and Akram in Numer Methods Part Differ Equ 33(2):445–466, 2017). It has been proved that the order of convergence of the proposed method is six, which is two orders of magnitude higher than the other spline collocation methods.","PeriodicalId":15034,"journal":{"name":"Journal of Applied Mathematics and Computing","volume":"17 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142257444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, when the mapping is Lipschitz continuous, we propose an improved subgradient extragradient algorithm with self-adaptive step-size (ISEGS for short). In ISEGS, the next iteration point is obtained by projecting sequentially the current iteration point onto two different half-spaces, and only one projection onto the feasible set is required in the process of constructing the half-spaces per iteration. The self-adaptive technique allows us to determine the step-size without using the Lipschitz constant. Second, we extend our algorithm into the case where the mapping is merely continuous. The Armijo line search approach is used to handle the non-Lipschitz continuity of the mapping. The global convergence of both algorithms is established without monotonicity assumption of the mapping. The computational complexity of the two proposed algorithms is analyzed. Some numerical examples are given to show the efficiency of the new algorithms.\u0000","PeriodicalId":15034,"journal":{"name":"Journal of Applied Mathematics and Computing","volume":"18 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142223495","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper first introduces generalized Dombi operational laws for p,q-ROF numbers. Utilizing these laws, we develop the p,q-ROF generalized Dombi weighted average (p,q-ROFGDWA) operator, the p,q-ROF generalized Dombi weighted geometric (p,q-ROFGDWG) operator, and their ordered weighted forms. We thoroughly examine the desirable properties and special cases of these new aggregation operators. Subsequently, we devise a multiple-criteria group decision-making method based on the p,q-ROFGDWA and p,q-ROFGDWG operators. Also an example regarding the selection of infectious medical waste treatment technology in Lahore, Pakistan is provided to exemplify the practicality and effectiveness of the developed model. The obtained results are then compared with other relevant methods, highlighting the efficacy and authenticity of the propound approach. Additionally, sensitivity analysis is performed to verify the suggested method’s stability. The findings indicate that the framed approach delivers robust and credible results for determining the ideal healthcare waste treatment technology.","PeriodicalId":15034,"journal":{"name":"Journal of Applied Mathematics and Computing","volume":"2016 1","pages":""},"PeriodicalIF":2.2,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142177868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
