Persistent Homology for Labeled Datasets: Gromov-Hausdorff Stability and Generalized Landscapes

Yaoying Fu, Evgeniya Lagoda, Shiying Li +3

Techniques from metric geometry have become fundamental tools in modern mathematical data science, providing principled methods for comparing datasets modeled as finite metric spac…

Anchored symplectic embeddings

Michael Hutchings, Agniva Roy, Morgan Weiler +1

Given two four-dimensional symplectic manifolds, together with knots in their boundaries, we define an ``anchored symplectic embedding'' to be a symplectic embedding, together with…

A classification of infinite staircases for Hirzebruch surfaces

Nicki Magill, Ana Rita Pires, Morgan Weiler

The ellipsoid embedding function of a symplectic manifold gives the smallest amount by which the symplectic form must be scaled in order for a standard ellipsoid of the given eccen…

Torus knot filtered embedded contact homology of the tight contact 3-sphere

Jo Nelson, Morgan Weiler

Knot filtered embedded contact homology was first introduced by Hutchings in 2015; it has been computed for the standard transverse unknot in irrational ellipsoids by Hutchings and…

Four-periodic infinite staircases for four-dimensional polydisks

Caden Farley, Tara Holm, Nicki Magill +4

The ellipsoid embedding function of a symplectic four-manifold measures the amount by which its symplectic form must be scaled in order for it to admit an embedding of an ellipsoid…

Staircase Patterns in Hirzebruch Surfaces

Nicki Magill, Dusa McDuff, Morgan Weiler

The ellipsoidal capacity function of a symplectic four manifold measures how much the form on must be dilated in order for it to admit an embedded ellipsoid of eccentricity…

Infinite staircases for Hirzebruch surfaces

Maria Bertozzi, Tara S. Holm, Emily Maw +4

We consider the embedding capacity functions for symplectic embeddings of ellipsoids of eccentricity into the family of nontrivial rational Hirzebruch surfaces $H_…

Embedded contact homology of prequantization bundles

Jo Nelson, Morgan Weiler

The 2011 PhD thesis of Farris demonstrated that the ECH of a prequantization bundle over a Riemann surface is isomorphic as a Z/2Z-graded group to the exterior algebra of the homol…

Mean action of periodic orbits of area-preserving annulus diffeomorphisms

Morgan Weiler

An area-preserving diffeomorphism of an annulus has an "action function" which measures how the diffeomorphism distorts curves. The average value of the action function over the an…

Pattern Avoidance in Poset Permutations

Sam Hopkins, Morgan Weiler

We extend the concept of pattern avoidance in permutations on a totally ordered set to pattern avoidance in permutations on partially ordered sets. The number of permutations on $P…
