Geodesically Complete Curvature-Bounce Inflation

Damien A. Easson · 2026

The early universe need not be described by an incomplete inflationary phase connected to a separate, more exotic prehistory. Recent results show that, within non-static FRW cosmology, only positive s…

A positive definite formulation of vacuum decay with reduced symmetry

Jose R. Espinosa, Ryusuke Jinno, Thomas Konstandin, Shogo Matake, Taiga Miyachi · 2026

The Euclidean bounce for vacuum decay enjoys an $O(4)$ symmetry that is lost in the presence of impurities than can catalyze the decay. We present a formulation for the calculation of the tunneling de…

Intermediate curvature and splitting theorem

Jingche Chen, Han Hong · 2026

In this paper, we prove several rigidity results for complete noncompact manifolds with nonnegative intermediate curvatures. We show that when either $3\leq n\leq 5$, $1\leq m\leq n-1$, or $6\leq n\le…

Brill-Noether theory for totally ramified covers of the projective line

Daksh Aggarwal · 2026

Given a curve $C$ that is a degree $k$ cover $C \to \mathbb{P}^1$ totally ramified at two points $p$ and $q$, we can seek to understand the space of degree $d$ line bundles on $C$ with prescribed rami…
