In standard cosmology, comoving distance and proper distance (or physical distance) are two closely related distance measures used by cosmologists to define...

In mathematical physics, the causal structure of a Lorentzian manifold describes the possible causal relationships between points in the manifold. Lorentzian...

[non-primary source needed] The collection of all algebraic structures of a given type will usually be a proper class. Examples include the class of all groups,...

when a single developer works on the entire codebase, a proper separation of the view from the model is more productive, as the user interface typically changes...

In mathematical logic, and particularly in its subfield model theory, a saturated model M is one that realizes as many complete types as may be "reasonably...

intelligence (AI), a foundation model (FM), also known as large X model (LxM), is a machine learning or deep learning model trained on vast datasets so that...
