Signed GLMY Homology of Signed Graphs via Double Covers
Shuliang Bai, Jingyan Li, Shing-Tung Yau
We define a signed GLMY chain complex over for signed digraphs using sheet-labelled regular paths. The complex is naturally isomorphic to the deck anti-invariant subco…
MoFE: A Novel Mixture-of-Experts Framework with Fourier Neural Operators for Cryptocurrency Forecasting
Bowen Liu, Mingming Sun
Forecasting cryptocurrency prices remains a formidable challenge due to inherent non-stationarity, abrupt regime shifts, and multi-scale stochastic dependencies. Conventional deep…
Remembering George Smoot
John Berliner, Tom Broadhurst, Martin Bucher +31
George Smoot (1945-2025) was a major figure in observational cosmology, particularly through his role in the precision measurement of the CMB dipole and the discovery of the primor…
Pitching Cosmic Curveballs: Environmental Effects on Extreme-Mass-Ratio Inspirals with Spinning Secondaries
Leif Lui, Lisa V. Drummond, Alejandro Torres-Orjuela
Much like the aerodynamic deflection of a spinning curveball, a rotating secondary in an extreme-mass-ratio inspiral (EMRI) experiences Magnus and lift forces, in addition to the s…
Hyperinvariant subspaces of hyponormal operators: A constructive decomposition approach
Norberto Clemente, Eva A. Gallardo-Gutiérrez
It is shown that any hyponormal operator on an infinite-dimensional separable Hilbert space that admits a decomposition \( T = R + V \), where \( R \) is tridiagonal and \( V \) is…
Exact solution for a periodically driven magnetic multilayer system
P. I. Naumkin, A. V. Nikolaev, L. L. Tao +1
Periodic driving serves as an effective method for controlling the properties of physical systems. Called "Floquet engineering," it is a broad field of theoretical and experimental…
