When the functions (D_{i}, S_{i}, f_{i}, g_{i}) ((i=1,2)) belong to (C^{2}) fulfilling some suitable hypotheses, we study the global existence and boundedness of classical solutions for the above system and find that under the case of (tau =1) or (tau =0), either the higher-order nonlinear diffusion or strong logistic damping can prevent blow-up of classical solutions for the problem. In addition, when the functions are replaced to Lotka–Volterra competitive kinetic functional response term and linear signal generations, by constructing some appropriate Lyapunov functionals, we show that the solution convergences to the constant steady state in (L^{infty }(Omega )) in the case of (a_1, a_2 in (0,1)) or (a_1 ge 1>a_2 > 0) under some more concise conditions than [2], which improved the existing conditions to some extent.","PeriodicalId":501481,"journal":{"name":"Zeitschrift für angewandte Mathematik und Physik","volume":"36 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142255912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model is particularly useful for studying physical systems with violated symmetries, as it provides insights into their behavior. To solve the ((2+1) {mathfrak {q}})-deformed equation for specific parameter values, the (({mathfrak {H}}+frac{{mathcal {G}}^{prime }}{ {mathcal {G}}^{2}}))-expansion approach is employed. This technique generates analytical solutions that reveal valuable information about the system’s dynamics and behavior. These solutions offer insights into the underlying mathematics and deepen the understanding of the system’s properties. To validate the accuracy of the analytical solutions, the finite difference technique is also used to find a numerical solution to the ({mathfrak {q}})-deformed equation. This numerical approach ensures the correctness of the solutions and enhances the reliability of the results. Tables and graphics are presented in the publication to aid comprehension and comparison. These visuals improve the clarity and interpretability of the data, allowing readers to better understand the similarities and differences between the analytical and numerical solutions.","PeriodicalId":501481,"journal":{"name":"Zeitschrift für angewandte Mathematik und Physik","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142224638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
