The field of numerical methods for partial differential equations is witnessing significant developments, driven by the need for more accurate and efficient solutions to complex problems. Researchers are exploring innovative techniques to improve the accuracy and robustness of numerical methods, such as the use of machine learning algorithms, new finite element methods, and advanced discretization techniques. One notable trend is the increasing use of data-driven approaches to solve partial differential equations, which has led to the development of novel methods that can achieve high accuracy on coarse meshes. Another area of focus is the development of more efficient and stable numerical methods for solving time-dependent problems, including the use of tensor neural networks and subordination-based approximations. Noteworthy papers in this area include the work on entropy stable shock capturing for high-order DGSEM on moving meshes, which demonstrates the potential for improved accuracy and stability in simulations of complex flows. The paper on learning high-accuracy numerical schemes for hyperbolic equations on coarse meshes is also significant, as it shows how data-driven approaches can be used to develop more efficient and accurate numerical methods.
