Tangents to Lipschitz and Sobolev images
Matthew Badger, Jared Krandel, Vyron Vellis
We develop geometric versions of Rademacher and Calderon type differentiability theorems in two categories. A special case of our results is that for any Lipschitz or continuous $W…
A Smooth Intrinsic Flat Limit of with Negative Curvature
Jared Krandel, Paul Sweeney
In 2014, Gromov asked if nonnegative scalar curvature is preserved under intrinsic flat convergence. Here we construct a sequence of closed oriented Riemannian -manifolds, $n\ge…
Weak Carleson conditions in uniformly rectifiable metric spaces: the WCD and alpha numbers
Jared Krandel
We investigate characterizations of uniformly rectifiable (UR) metric spaces by so-called weak Carleson conditions for flatness coefficients which measure the extent to which Hausd…
Lipschitz decompositions of domains with bilaterally flat boundaries
Jared Krandel
We study classes of domains in with sufficiently flat boundaries that admit a decomposition or covering of bounded overlap by Lipschitz graph domains…
Iterating the Big--Pieces operator and larger sets
Jared Krandel, Raanan Schul
We show that if an Ahlfors-David regular set of dimension has Big Pieces of Big Pieces of Lipschitz Graphs (denoted usually by ), then wher…
The Traveling Salesman Theorem for Jordan Curves in Hilbert Space
Jared Krandel
Given a metric space , an Analyst's Traveling Salesman Theorem for gives a quantitative relationship between the length of a shortest curve containing any subset $E\subseteq…
