A study of the threedimensional quasigeostrophic system
(20190618)The threedimensional quasigeostrophic system is a set of equations used to model atmospheric and oceanic circulation. We shall consider both inviscid and viscous variations of the underlying model, which may be posed on ... 
A weighty theorem of the heart for the algebraic Ktheory of higher categories
(20170504)We introduce the notion of a bounded weight structure on a stable [infinity symbol]category and prove a generalization of Waldhausen’s sphere theorem for the algebraic Ktheory of higher categories. The algebraic Ktheory ... 
Abelian ChernSimons theory with toral gauge group, modular tensor categories, and group categories
(200808)Classical and quantum ChernSimons with gauge group U(1)N were classified by Belov and Moore in [BM05]. They studied both ordinary topological quantum field theories as well as spin theories. On the other hand a correspondence ... 
About the largest subsolution for a free boundary problem in R²
(201012)We analyze the geometry and regularity of the largest subsolution of a Free Boundary Problem. We showed that the largest subsolution is a viscosity solution of (1) with Lipschitz and NonDegenerate properties under a very ... 
Academic math mindset interventions in firstyear college calculus
(20170721)Freshman calculus is in the policy spotlight. This gateway course’s welldocumented high failure rates impede students’ timely completion of baccalaureate degrees. The Mathematical Association of America launched a largescale ... 
Accuracy of RNASeq and its dependence on sequencing depth
(BMC Bioinformatics, 20120824)Background: The cost of DNA sequencing has undergone a dramatical reduction in the past decade. As a result, sequencing technologies have been increasingly applied to genomic research. RNASeq is becoming a common technique ...

Adiabatic limits of the Hermitian YangMills equations on slicewise stable bundles
(2002)A formal limit of the Hermitian YangMills Equations on a SU(2) bundle over a product of two Riemann surfaces yields the Adiabatic Equations when the metric of the first surface is stretched ad infinitum. This thesis ... 
Admixture Correction in the Outgroupf3 Statistic
(201805)Genetic inheritance can be studied within a purely genetic scope. However, this eliminates part of the picture. The field of genetics is often thought of as a natural science with little in common with fields of social ... 
Agents' agreement and partial equilibrium pricing in incomplete markets
(200812)We consider two riskaverse financial agents who negotiate the price of an illiquid indivisible contingent claim in an incomplete semimartingale market environment. Under the assumption that the agents are exponential ... 
Algebra readiness : building strong foundations through conceptual understanding
(201108)Algebra readiness has been a topic of much research and debate. This report summarizes findings pertaining to how researchers and experts in the field of mathematics education define the term algebra readiness. The Southern ... 
Alternative estimation approaches for some common Item Response Theory models
(201008)In this report we give a brief introduction to Item Response Theory models and multilevel models. The general assumptions of two classical Item Response Theory, 1PL and 2PL models are discussed. We follow the discussion ... 
An analogue of the KorkinZolotarev lattice reduction for vector spaces over number fields
(201008)We show the existence of a basis for a vector space over a number field with two key properties. First, the nth basis vector has a small twisted height which is bounded above by a quantity involving the nth successive ... 
Analysis of a DarcyStokes system modeling flow through vuggy porous media
(2004)Our goal is to accurately model flow through subsurface systems composed of vuggy porous media. A vug is a small cavity in a porous medium which is large relative to the intergranular pore size. A vuggy porous medium is ... 
Analysis of errors and improvements in numerical approximations and methods in secondary mathematics curriculum
(201308)This report discusses three topics relating to errors of numerical methods and to improvements of numerical approximations. The introduction connects these topics to the secondary mathematics curriculum. The three chapters ... 
Analysis of geometric flows, with applications to optimal homogeneous geometries
(201105)This dissertation considers several problems related to Ricci flow, including the existence and behavior of solutions. The first goal is to obtain explicit, coordinatebased descriptions of Ricci flow solutionsespecially ... 
Analysis of Ricci flow on noncompact manifolds
(201305)In this dissertation, we present some analysis of Ricci flow on complete noncompact manifolds. The first half of the dissertation concerns the formation of TypeII singularity in Ricci flow on [mathematical equation]. For ... 
Analysis of the real line
(201108)The purpose of this report is to describe the course, Analysis of the Real Line, taught at The University of Texas at Austin. Course materials are presented using the inquiry based learning method. Students work a series ... 
The AndréQuillen spectral sequence for prelogarithmic ring spectra
(201508)We discuss an AndréQuillen spectral sequence and an étale descent theorem for prelogarithmic ring spectra.
