APROXIMACIONES BASADAS EN DISTANCIAS ERGÓDICAS Y MEZCLADO CAÓTICO EN PILAS DE LIXIVIACIÓN

Avances en Ciencias e Ingeniería
This study explores the application of ergodic distances and the use of chaotic mixing in heap leaching, focusing on the dynamics of strongly mixing systems where Koopman approximations may exhibit spurious eigenvalues.

A linear test for global nonlinear controllability

Comptes Rendus. Mathématique
It is known that if a nonlinear control affine system without drift is bracket generating, then its associated sub-Laplacian is invertible under some conditions on the domain. In this note, we investigate the converse.

A Mathematical Framework for Modeling Global Value Chain Networks

Foundations
Global value chains (GVCs) have evolved into highly interconnected and geographically fragmented production networks, increasing exposure to systemic disruptions and revealing the limitations of static input–output and conventional network approaches ...

Koopman theory-inspired method for learning time advancement operators in unstable flame front evolution

Physics of Fluids
Predicting the evolution of complex systems governed by partial differential equations remains challenging, especially for nonlinear, chaotic behaviors. This study introduces Koopman-inspired Fourier neural operators and convolutional neural networks to learn solution advancement operators for flame front instabilities. By transforming data into a high-

Extended Kalman filter -- Koopman operator for tractable stochastic optimal control

The theory of dual control was introduced more than seven decades ago. Although it has provided rich insights to the fields of control, estimation, and system identification, dual control is generally computationally prohibitive. In recent years, however,
