Geodesic nets on the Euclidean plane and closed geodesic nets on Euclidean surfaces

Ivan Frolov, Denis Gorodkov, Dmitrii Korshunov +1

We prove that if is a closed Riemannian surface of diameter and area with sectional curvature in the interval, then a closed geodesic net of length has at…

Small separators, upper bounds for -widths, and systolic geometry

Sergey Avvakumov, Alexander Nabutovsky

We investigate the dependence on the dimension in the inequalities that relate the Euclidean volume of a closed submanifold with its -width $W^{…

Boxing inequalities in Banach spaces and Riemannian manifolds

Sergey Avvakumov, Alexander Nabutovsky

We prove the following result: For each closed -dimensional manifold in a (finite or infinite-dimensional) Banach space , and each positive real there exists a…

Geodesic nets on non-compact Riemannian manifolds

Gregory R. Chambers, Yevgeny Liokumovich, Alexander Nabutovsky +1

A geodesic flower is a finite collection of geodesic loops based at the same point that satisfy the following balancing condition: The sum of all unit tangent vectors to all ge…

Sweepouts of closed Riemannian manifolds

Alexander Nabutovsky, Regina Rotman, Stéphane Sabourau

We show that for every closed Riemannian manifold there exists a continuous family of -cycles (defined as finite collections of disjoint closed curves) parametrized by a sphere…

Linear bounds for constants in Gromov's systolic inequality and related results

Alexander Nabutovsky

Let be a closed Riemannian manifold. Larry Guth proved that there exists with the following property: if for some the volume of each metric ball of radius is…
