Description
In this talk, I will introduce the polyLCDM model, a simple, extensive framework that classifies a set of modified gravity models, resulting to cosmological observables that can fit data, and tell us which classes are viable according to observations. Furthermore, I will discuss modified gravity and cosmology models based on Functors of Actions Theories (FAT) which predict actionions, actionic theories/cosmologies, Advanced Tensor Theories (ATT) which re-introduce fractional calculus into theories/cosmologies, and Advanced Manifold Metric Pairs (AMMM) which expand advanced topological cosmologies. These are advanced mathematical frameworks that expand the classes and reclassifies standard models such as modified gravity, dark energy, inflation,, string theory, generalised symmetries, quantum field theories, AdS/CFT correspondence and possibly resolving cosmic tensions, and Black Holes Singularities.
