Compact Manifolds with Unbounded Nilpotent Fundamental Groups and Positive Ricci Curvature

Elia Bruè, Aaron Naber, Daniele Semola

It follows from the work of Kapovitch and Wilking that a closed manifold with nonnegative Ricci curvature has an almost nilpotent fundamental group. Leftover questions and conjectu…

Six dimensional counterexample to the Milnor Conjecture

Elia Bruè, Aaron Naber, Daniele Semola

We extend our previous work by building a smooth complete manifold with and whose fundamental group is infinitely…

Fukaya-Yamaguchi Conjecture in Dimension Four

Elia Bruè, Aaron Naber, Daniele Semola

Fukaya and Yamaguchi conjectured that if is a manifold with nonnegative sectional curvature, then the fundamental group is uniformly virtually abelian. In this short note we…

Monotonicity formula and stratification of the singular set of perimeter minimizers in RCD spaces

Francesco Fiorani, Andrea Mondino, Daniele Semola

The goal of this paper is to establish a monotonicity formula for perimeter minimizing sets in RCD(0,N) metric measure cones, together with the associated rigidity statement. The a…
