The Steklov spectrum of convex polygonal domains II: investigating spectral determination

Emily B. Dryden, Carolyn Gordon, Javier Moreno, Julie Rowlett, Carlos Villegas-Blas · 2026

The extent to which the geometry of an object is determined by some associated spectral data is a longstanding problem. We investigate this problem in the context of the Steklov spectrum, focusing on …

Random 0/1-polytopes expand rapidly

He Guo, Istvan Tomon · 2026

A 0/1-polytope is the convex hull of a subset $V\subseteq \{0,1\}^n$. A celebrated conjecture of Mihail and Vazirani asserts that the graph of every 0/1-polytope has edge-expansion at least 1. In this…

Makkai's lost proof of projectivity of N in the free topos

Henrik Forssell, Peter LeFanu Lumsdaine, Andrew W. Swan · 2026

We give a categorical proof of the projectivity of $N$ in the free topos -- in proof-theoretic terms, the rule of countable choice for intuitionistic higher-order logic -- based on the unpublished pro…

Invariant idempotent $\ast$-measures for generalized iterated function systems

Natalia Mazurenko, Mykhailo Zarichnyi · 2026

The notion of $\ast$-measure on a compact Hausdorff space can be defined for arbitrary continuous triangular norm $\ast$. The well-known Hutchinson-Barnsley theory deals with the iterated function sys…

Plane Floer homology and the odd Khovanov homology of 2-knots

Dean Spyropoulos, Rithwik Susheel Vidyarthi, Chen Zhang · 2026

We prove a conjecture of Migdail and Wehrli regarding the odd Khovanov cobordism maps associated to knotted spheres. Our key tool is Daemi's plane Floer homology, which we use in place of a Lee deform…
