Abstract:
In this thesis, we examine the geometry of fractals and metric spaces. We study
the question of which fractal metric spaces can be embedded into Banach spaces up to a
certain distortion.
Our main focus is on a metric space introduced by Urs Lang and Conrad Plaut in "Bi-Lipschitz
Embeddings of Metric Spaces into Space Forms," which we refer to as the Diamond Graph Fractal. By modifying the construction methods defined by Lang and Plaut , we develop a
Generalized Diamond Graph Fractal and study whether the space converges in the Gromov-Hausdorff
distance, satisfies the doubling property, and whet her it can be Bi-Lipschitzly embedded
into certain Banach spaces with given properties. Our approach to the Bi-Lipschitz embedding
problem is to generalize the argument of Lang and Plaut , which involves the quadrilateral
inequality, a property of namely Hilbert space.
In addition, we also study and explain an argument in the paper "On the Geometry of
the Countably Branching Diamond Graphs" by Florent Baudier et . Al., which involves
a related class of graphs and "asymptotic midpoint uniform convexity", a property that the
norm of certain Banach spaces, including Hilbert spaces, can satisfy. Our goal, by comparing
these two arguments, is to better understand the properties of Banach spaces and how these
properties interact with the geometry of certain fractal metric spaces.
