Frobenius algebra in nLab
A Frobenius algebra is a vector space equipped with the structures both of an algebra and of an a coalgebra in a compatible way, where the compatibility is different from (more “topological” than) that in a bialgebra/Hopf algebra:

You need a lot of data points to understand a new model, and what you have.

Our Theory-of-Everything, OPH, completely unifies the Standard Model with gravity: A SINGLE constant determines both Newton's constant G and the particle spectrum. Mass-less photons, gravitons and gluons emerge for free. https://t.co/dUh6TLAlop— Bernhard Mueller (@muellerberndt) April 4, 2026
Dark matter as a Ricci soliton
In this paper we consider clumped baryonic matter as a spherically symmetric barotropic fluid associated with a compact four-dimensional Einstein manifold with a four-radius that is determined by the fluid density. We further investigate the properties of these matter generated manifolds and show that because of their homogeneity and isotropy they exhibit FLRW metric properties and expand with cosmic time. At low densities such as those encountered in star clusters, galaxies and galactic clusters, these manifolds are large and show the same properties that are currently attributed to dark matter.
