Early universe cosmology, effective supergravity, and invariants of algebraic forms
The presence of light scalars can have profound effects on early universe cosmology, influencing its thermal history as well as paradigms like inflation and baryogenesis. Effective supergravity provides a framework to make quantifiable, model-independent studies of these effects. The Riemannian curvature of the K\"ahler manifold spanned by scalars belonging to …
