Surface Entropy of Shifts of Finite Type
… We demonstrate that much like entropy, the finiteness of surface entropy is a conjugacy invariant and is a tool in the classification of subshifts. We develop a tiling algorithm related to continued fractions which allows us to prove a continuity result about surface entropy in the 2-D case, …

d-bar continuity beyond subshifts of finite type
… weak*-topology. For Topological Markov Shifts on finite alphabets, potentials with summable variations have a unique equilibrium state. One can quickly prove that the map that sends a potential to its unique equilibrium state is continuous in the weak*-topology. For full shifts on a finite …

Flat surfaces of finite type in the 3-sphere
We introduce the notion of flat surfaces of finite type in the 3- sphere, give the algebro-geometric description in terms of spectral curves and polynomial Killing fields, and show that finite type flat surfaces generated by curves on S2 with periodic curvature functions are dense in the space of …

Minimal Presentations of Sofic Shifts and Properties of Periodic-Finite-Type Shifts
… study of sofic shifts, which are sets of bi-infinite sequences that can be presented using labeled directed graphs called presentations. In this thesis, we will primarily focus on two classes of sofic shifts, namely shifts of finite type (SFT’s) and periodic-finite-type shifts (PFT’s), and …

Standard Closure Operations on Several Rings of Dimension One
… has shown a correspondence between the set of finite-type semistar operations of a ring and the finite-type standard closures of a ring. I will classify the set of finite-type standard closures on several rings of dimension one.

The Pure Virtual Braid Group is Quadratic
… of a (not necessarily homomorphic) universal finite type invariant for G. Thus the PVH Criterion also implies the existence of a universal finite type invariant for the group G. We apply the PVH Criterion to the group algebra of the pure virtual braid group (also known as the quasi-triangular …

Equilibrium Measures for Symbolic Spaces Using Dimension Theory
… formalism is well developed for subshifts of finite type. However, less is known about equilibrium measures for more general shift spaces beyond existence and, in some cases, uniqueness. Rather than constructing equilibrium measures as a limit of a sequence of measures or via a fixed point …

The symplectic topology of Stein manifolds
… manifold which is not symplectomorphic to any finite type Stein manifold. The second result states that in each dimension > 3 there are infinitely many finite type exotic Stein manifolds which are pairwise distinct as symplectic manifolds.

The Boundary Behavior of Holomorphic Functions
… theory of several complex variables, the Fatou type problems, the Lindel\"{o}f principle, and inner functions have been well studied for strongly pseudoconvex domains. In this thesis, we are going to study more generalized domains, those of finite type. In Chapter 2 we show that there is no …

The Multivariable Alexander Polynomial on Tangles
… following the previous proofs that the MVA is of finite type we give a new definition for its weight system which can be computed as the determinant of a matrix created from local information. This is an improvement on previous definitions as it is directly computable (not defined recursively) and …

Dynamical Systems and Matching Symmetry in Beta-Expansions
… to when T<sub>β,⍺</sub> generates a subshift of finite type. We prove the set of ⍺ in the parameter space for which T<sub>β,⍺</sub> exhibits matching is symmetric and analyze some examples where the symmetry is both apparent and useful in finding a dense set of ⍺ for which T<sub>β,⍺</sub> …

Minimal Models and Riemannian Foliations
… minimal model has an underlying rational form of finite type, then it can be realized in rational homotopy by a fibration of finite CW complexes. As a consequence, based on results of Gottlieb and Chern-Hirzebruch-Serre, a signature product formula is obtained.

Uniform bounds in F-finite rings and their applications /
… in characteristic p rings which are either F-finite or essentially of finite type over an excellent local ring. These uniform bounds are then used to show that the Hilbert-Kunz length functions and the normalized Frobenius splitting numbers defined on the spectrum of a ring converge uniformly …

Rigidity of length functions over strata of flat metrics
… (semi-translation structures) on surfaces of finite type. We provide a necessary and sufficient condition for a set of simple closed curves to be spectrally rigid over a stratum with enough complexity, extending a result of Duchin-Leininger-Rafi. Specifically, for any stratum with more …

Applications of graded methods to cluster variables in arbitrary types
… examples of cluster algebras, primarily of infinite type. We start by considering two classes of finite type cluster algebras: those of type Bn and Cn. We give the number of cluster variables of each occurring degree and verify that the grading is balanced. These results complete a …

The noncommutative geometry of ultrametric cantor sets

Arithmetic duality in algebraic K-theory
… or point (meaning a regular separated scheme of finite type over Z which is connected and of Krull dimension </= 1). We define a compactly-supported variant Kc(X) of the algebraic K-theory spectrum K(X), and establish the basic functoriality of Kc. Briefly, K, behaves as if it were dual to K. …

Derived mapping spaces as models for localizations by Jennifer E. French.

The geometry of end-periodic mapping tori
Let $S$ be a boundaryless infinite-type surface with finitely many ends and consider an end-periodic homeomorphism $f$ of S. The end-periodicity of $f$ ensures that $M_f$, its associated mapping torus, has a compactification as a $3$-manifold with boundary; further, if $f$ is atoroidal, then $M_f$ …
