The recent publications in the field of computational physics and applied mathematics reveal a strong trend towards the development of innovative numerical methods and algorithms that enhance the efficiency, accuracy, and scalability of solving complex wave scattering, electromagnetic, and fluid dynamics problems. A significant focus is on leveraging machine learning techniques to accelerate computations, particularly in the context of low-rank matrix factorization and the solution of integral equations for electromagnetic scattering. Additionally, there is a notable advancement in the application of isogeometric analysis (IGA) and finite element methods (FEM) for solving high-order differential equations and wave propagation problems, with an emphasis on local refinement and adaptive strategies to improve computational efficiency. The integration of domain decomposition strategies and the development of fully differentiable solvers for hydrodynamic sensitivity analysis represent a leap forward in handling complex boundary conditions and optimizing system designs. Furthermore, the exploration of spacetime wavelet methods and polarized spherical harmonics for nonlinear partial differential equations and polarized light transport, respectively, showcases the field's expansion into novel mathematical frameworks for simulating intricate physical phenomena. The emphasis on stability, high-order accuracy, and parallelizability across these studies underscores the ongoing pursuit of robust computational tools capable of addressing the multifaceted challenges in modern scientific and engineering applications.
