This issue presents a collection of ten original research articles that bridge theoretical innovation and practical application in computational mathematics. Contributions advance core areas of numerical analysis, including high-order spectral approximations, novel methods for solving nonlinear integral and differential equations, and rigorous stability analyses.

Applied research explores dynamic models in ecology and economics, featuring bifurcation analysis of predator-prey systems and comparative studies on exchange rate and time series forecasting. Theoretical investigations enrich the issue with insights into structured matrices and fixed-point theory in generalized metric spaces.

Collectively, these ten articles provide a coherent snapshot of current progress, offering both robust methodological tools and insightful applications for researchers in applied mathematics and computational science.
