On Data-Driven Koopman Representations of Nonlinear Delay Differential Equations

arXiv CS.LG

ArXi:2604.03086v1 Announce Type: cross This work establishes a rigorous bridge between infinite-dimensional delay dynamics and finite-dimensional Koopman learning, with explicit and interpretable error guarantees. While Koopman analysis is well-developed for ordinary differential equations (ODEs) and partially for partial differential equations (PDEs), its extension to delay differential equations (DDEs) remains limited due to the infinite-dimensional phase space of DDEs.
