Plane embeddings of continua, and accessible points

Logan Hoehn ⟨loganh@nipissingu.ca⟩

Abstract:

A point $p$ in a plane continuum $X \subset \mathbb{R}^2$ is accessible if there exists an arc $A \subset \mathbb{R}^2$ such that $A \cap X = \{ p \}$. I will describe our recent results about plane embeddings of continua and their accessible points. Specifically, I will discuss arc-like continua (the Nadler-Quinn problem), Knaster continua, and Ingram’s atriodic triod-like continuum. This is joint work with Andrea Ammerlaan and Ana Anušić.
