Correlation networks in economics and finance: A review of methodologies and bibliometric analysis

Journal of Economic Surveys, Volume 39, Issue 3, Page 1252-1286, July 2025.
Abstract This paper presents an in‐depth review of the methodologies and innovations in the study of correlation networks in economics and finance. We explore the development of filtering algorithms and distance measures, emphasizing their critical role in extracting meaningful financial interconnections.

Continuity of HYM connections with respect to metric variations

Journal of the London Mathematical Society, Volume 112, Issue 1, July 2025.
Abstract We investigate the set of (real Dolbeault classes of) balanced metrics Θ$\Theta$ on a balanced manifold X$X$ with respect to which a torsion‐free coherent sheaf E$\mathcal {E}$ on X$X$ is slope stable. We prove that the set of all such [Θ]∈Hn−1,n−1(X,R)$[\Theta] \in H^{n - 1,n - 1}(X,\mathbb {R})$ is an open convex cone locally defined by a ...

A Time‐Adaptive Multirate Quasi‐Newton Waveform Iteration for Coupled Problems

International Journal for Numerical Methods in Engineering, Volume 126, Issue 12, 30 June 2025.
ABSTRACT We consider waveform iterations for dynamical coupled problems, or more specifically, PDEs that interact through a lower‐dimensional interface. We want to allow for the reuse of existing codes for the subproblems, called a partitioned approach.

A Novel Approach to Thermo‐Mechanically Coupled, Gradient‐Enhanced Damage Modeling

International Journal for Numerical Methods in Engineering, Volume 126, Issue 12, 30 June 2025.
ABSTRACT Thermo‐mechanical damage, such as thermal shock, is a common engineering problem. It constitutes a challenging problem that damage and temperature are conversely interacting with each other: Material damage leads to an increase in temperature due to energy dissipation; temperature also influences damage evolution.

Stencil Computations on AMD and Nvidia Graphics Processors: Performance and Tuning Strategies

Concurrency and Computation: Practice and Experience, Volume 37, Issue 12-14, 25 June 2025.
ABSTRACT Over the last ten years, graphics processors have become the de facto accelerator for data‐parallel tasks in various branches of high‐performance computing, including machine learning and computational sciences. However, with the recent introduction of AMD‐manufactured graphics processors to the world's fastest supercomputers, tuning ...
