The Puerto Rico coastline is a rectifiable curve!, Dr. Peter Cholak, University of Notre Dame, Tue, 11 March, 2025, 11:30 a.m. NCN II A-211
Abstract
More or less a bounded curve is rectifiable iff it has length. There is a criterion to determine if a curve is rectifiable involving the Jones β number.What is it? What are some examples of the β numbers of the coastline? Does any of this help us understand or control coastline erosion? While we will not exactly answer these questions we will explain what all these terms mean. Hopefully we will encourage everyone to learn more geometric measure theory! This will be a purely expository talk. But the speaker is always willing to talk (offline) about his related research. Post is here.
