    • The Amalgamated Free Product of Hyperfinite von Neumann Algebras 
      Redelmeier, Daniel (2012-07-16)
      We examine the amalgamated free product of hyperfinite von Neumann algebras. First we describe the amalgamated free product of hyperfinite von Neumann algebras over finite dimensional subalgebras. In this case the result ...
    • Investigation of Simple Linear Measurement Error Models (SLMEMS) with Correlated Data 
      Lu, Ming (2014-12-06)
      The primary goal of this research is to develop statistical methods to determine if observed real responses are adequately modeled by (possibly stochastic) simulation models that incorporate first-order autoregressive ...
    • K-Theoretic Dynamics and Finiteness in C*-Crossed Products 
      Rainone, Timothy (2015-08-11)
      This work explores the interplay of C*-dynamics and K-theory. More precisely, we study the extent to which various forms of finite-dimensional approximation properties of a topological nature, witnessed in reduced C*-crossed ...
    • Normalizers of Finite von Neumann Algebras 
      Cameron, Jan Michael (2010-10-12)
      For an inclusion N \subseteq M of finite von Neumann algebras, we study the group of normalizers N_M(B) = {u: uBu^* = B} and the von Neumann algebra it generates. In the first part of the dissertation, we focus on the ...
    • On the Interpolation of Smooth Functions via Radial Basis Functions 
      Hamm, Keaton P (2015-06-26)
      We consider the interpolatory theory of bandlimited functions at both the integer lattice and at more general point sets in Rd by forming interpolants which lie in the linear span of translates of a single Radial Basis ...
    • On Upper-triangular Forms in Tracial von Neumann Algebras 
      Noles, Joseph Clarke (2017-12-14)
      A classical theorem of Issai Schur states that any n×n matrix is unitarily equivalent to an upper-triangular matrix, and hence can be decomposed as the sum of a normal matrix and a nilpotent matrix. Dykema, Sukochev and ...
    • Perturbations of Certain Crossed Product Algebras by Free Groups 
      Chan, Wai (2015-05-27)
      Given two von Neumann algebras M and N acting on the same Hilbert space, d(M;N) is defined to be the Hausdor distance between their unit balls. The Kadison-Kastler problem asks whether two sufficiently close von Neumann ...
    • Refined error estimates for matrix-valued radial basis functions 
      Fuselier, Edward J., Jr. (Texas A&M University, 2007-09-17)
      Radial basis functions (RBFs) are probably best known for their applications to scattered data problems. Until the 1990s, RBF theory only involved functions that were scalar-valued. Matrix-valued RBFs were subsequently ...
    • Studies in Interpolation and Approximation of Multivariate Bandlimited Functions 
      Bailey, Benjamin Aaron (2012-10-19)
      The focus of this dissertation is the interpolation and approximation of multivariate bandlimited functions via sampled (function) values. The first set of results investigates polynomial interpolation in connection with ...
    • Szlenk Index, Upper Estimates, and Embedding in Banach Spaces 
      Causey, Ryan Michael (2014-08-07)
      We investigate the relationship between two notions, one which refers to a coordinate system and one which does not, of asymptotic domination by subsequences of a fixed basis. We use this relationship to prove the existence ...
    • Topics in living cell miultiphoton laser scanning microscopy (MPLSM) image analysis 
      Zhang, Weimin (Texas A&M University, 2006-10-30)
      Multiphoton laser scanning microscopy (MPLSM) is an advanced fluorescence imaging technology which can produce a less noisy microscope image and minimize the damage in living tissue. The MPLSM image in this research is the ...
    • Upper Estimates for Banach Spaces 
      Freeman, Daniel B. (2010-10-12)
      We study the relationship of dominance for sequences and trees in Banach spaces. In the context of sequences, we prove that domination of weakly null sequences is a uniform property. More precisely, if $(v_i)$ is a ...
