Analysis

This paper explores the behavior of Proca stars (hypothetical compact objects) within a theoretical framework that includes an infinite series of corrections to Einstein's theory of gravity.

Analysis

This paper presents three key results in the realm of complex geometry, specifically focusing on Kähler-Einstein (KE) varieties and vector bundles.
