Mono- and oligochromatic extreme-mass ratio inspirals

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Pau Amaro Seoane, Yiren Lin, Kostas Tzanavaris, , | Summary: The gravitational capture of a stellar-mass object by a supermassive black hole represents a unique probe of warped spacetime. The small object, typically a stellar-mass black hole, describes a very large number of cycles before crossing […]

Neural Downscaling for Complex Systems: from Large-scale to Small-scale by Neural Operator

Kavli Affiliate: Jing Wang | First 5 Authors: Pengyu Lai, Jing Wang, Rui Wang, Dewu Yang, Haoqi Fei | Summary: Predicting and understanding the chaotic dynamics in complex systems is essential in various applications. However, conventional approaches, whether full-scale simulations or small-scale omissions, fail to offer a comprehensive solution. This instigates exploration into whether modeling […]

Analysis of singular subspaces under random perturbations

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, , , , | Summary: We present a comprehensive analysis of singular vector and singular subspace perturbations in the context of the signal plus random Gaussian noise matrix model. Assuming a low-rank signal matrix, we extend the Wedin-Davis-Kahan theorem in a fully generalized manner, applicable […]
