Asking the World: Generalist Physical Reasoning through Agentic World Modeling and Probing

Physical reasoning from video requires inferring latent physical properties and dynamics beyond direct observation. Direct VLM inference remains unreliable on complex physical tasks without explicit modeling and validation, while predefined tool pipelines rely on task- and domain-specific priors that limit generalizati...

Beyond Arbitrary Geometry: Topology Generalization In neural PDE Operators

Topology is established as a distinct generalization axis beyond arbitrary-geometry compatibility and influence extends across the Hodge spectrum rather than remaining confined to the harmonic kernel, and global, low-frequency structural priors may help organize predictions in the faster-decaying complementary componen...
