arXiv:2602.11288v1 Announce Type: cross Abstract: We derive a novel two-field four-dimensional integrable field theory (IFT) from 6d holomorphic Chern-Simons theory on twistor space. The four-dimensional...
arXiv:2602.11312v1 Announce Type: cross Abstract: We construct a new nonlinear deformed Schr\"odinger structure using a nonlinear derivative operator which depends on a parameter $q$. This...
arXiv:2602.11332v1 Announce Type: cross Abstract: In recent years, artificial neural networks have been increasingly studied as feedback controllers for guidance problems. While effective in complex...
arXiv:2602.11378v1 Announce Type: cross Abstract: Projection-based Reduced Order Models (ROMs) are often deployed as static surrogates, which limits their practical utility once a system leaves...
arXiv:2602.11511v1 Announce Type: cross Abstract: Unified representation learning for multi-source data integration faces two important challenges: blockwise missingness and blockwise signal heterogeneity. The former arises...

arXiv:2602.11696v1 Announce Type: cross Abstract: Anomaly matching for continuous symmetries has been the primary tool for establishing symmetry enforced gaplessness - the phenomenon where global...
arXiv:2602.11711v1 Announce Type: cross Abstract: This article addresses the issue of estimating observation parameters (response and error parameters) in inverse problems. The focus is on...
arXiv:2602.11716v1 Announce Type: cross Abstract: In 2015, Kawarabayashi and Kreutzer proved the Directed Grid Theorem - the generalisation of the well-known Excluded Grid Theorem to...
arXiv:2602.11772v1 Announce Type: cross Abstract: In this paper we study the inverse eigenvector centrality problem on directed graphs: given a prescribed node centrality profile, we...
arXiv:2602.11773v1 Announce Type: cross Abstract: For a directed graph $G$, and a linear order $\ll$ on the vertices of $G$, we define backedge graph $G^\ll$...
arXiv:2602.11835v1 Announce Type: cross Abstract: We consider the problem of finding a Nash equilibrium (NE) in a general-sum game, where player $i$'s objective is $f_i(x)=f_i(x_1,...,x_n)$,...
