First, we establish a dynamical system linked to the equation by employing the Galilean transformation. By employing the system of complete discriminant of the polynomial technique, we methodically develop single traveling wave solutions for the governing model. Our solutions encompass hyperbolic, rational, and trigonometric forms, Jacobian elliptic functions, and various solitary wave solutions, along with transitions of Jacobian elliptic functions to periodic and hyperbolic solutions. Furthermore, we investigate the bifurcation processes that are intrinsic to the derived system using concepts from the theory of planar dynamical systems. Additionally, the existence of chaotic behaviors in the governing model is investigated by adding a perturbed term into the resulting dynamical system and presenting various two and three dimensional phase pictures. We also conduct sensitivity analyses to understand how various initial conditions affect the governing model. The proposed bifurcation and sensitivity analyses provide a framework for predicting and managing soliton behaviour in noisy environments, with possible applications in optical communications, fluid dynamics, and quantum mechanics. To illustrate our findings, we include several graphics that vividly demonstrate the influence of noise. These graphics reveal distinct patterns of random fluctuations, demonstrating the tremendous impact of stochastic forces across different systems and scenarios.</p></div>","PeriodicalId":48860,"journal":{"name":"Analysis and Mathematical Physics","volume":"15 3","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13324-025-01077-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144074068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"数学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently an analogue was obtained for quantum graphs relating the number of spanning trees to the spectral determinant of a Laplacian acting on functions on a metric graph with standard (Neumann-like) vertex conditions [20]. This result holds for quantum graphs where the edge lengths are close together. A quantum graph where the edge lengths are all equal is called equilateral. Here we consider equilateral graphs where we perturb the length of a single edge (almost equilateral graphs). We analyze the spectral determinant of almost equilateral complete graphs, complete bipartite graphs, and circulant graphs. This provides a measure of how fast the spectral determinant changes with respect to changes in an edge length. We apply these results to estimate the width of a window of edge lengths where the connection between the number of spanning trees and the spectral determinant can be observed. The results suggest the connection holds for a much wider window of edge lengths than is required in [20].</p></div>","PeriodicalId":48860,"journal":{"name":"Analysis and Mathematical Physics","volume":"15 3","pages":""},"PeriodicalIF":1.4,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949456","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}
