  • Age-dependent Branching Processes and Applications to the Luria-Delbrck Experiment 

    Oveys, Hesam (University of Missouri--Columbia, 2015)
    Microbial populations adapt to their environment by acquiring advantageous mutations, but in the early twentieth century, questions about how these organisms acquire mutations arose. The experiment of Salvador Luria and ...
  • Counterexamples to Strichartz Type Inequalities 

    Alhazaa, Khalifa (University of Missouri--Columbia, 2013)
    The study of Strichartz s inequality is very important in the theory of nonlinear Shrodinger equations. The inequalities do not hold for all choice of constants. Many cases were settled. for instance, some cases were settled ...
  • Quasi-Metric Geometry 

    Brigham, Dan ([University of Missouri--Columbia], 2014)
  • Expectation of p-norm of random matrices with heavy tails 

    Vaidyanathan, Chandrasekar, 1975- ([University of Missouri--Columbia], 2014)
    The p-norm (p > 2) of a random matrix whose entries are gaussian, subgaussian and log concave have been studied previously. We conjecture the following generalization of the above results for heavy tailed random matrices: ...
  • On unimodality of Hilbert functions of Artinian level algebras of codimension 3 and type 2 and 3 

    D'Orazio, Valeria, 1979- ([University of Missouri--Columbia], 2014)
    We prove the unimodality of the Hilbert Function for some classes of codimension three graded algebras of Cohen-Macaulay types 2 and 3. The method of proof uses the explicit structure theorems similar to the structure ...
  • Results on the Collatz Conjecture 

    Hardwick, Samuel ([University of Missouri--Columbia], 2014)
    Given a starting value, we can create a sequence using the rule that if the previous number, x, is even, then the next number is [x/2], and if the previous number, x, is odd, then the next number is [(3x+1)/2]. The collatz ...
  • Generating sequences of valuations and applications 

    Vinh, Pham An, 1984- ([University of Missouri--Columbia], 2014)
  • Irrational behavior of algebraic discrete valuations 

    Sanyal, Soumya Deepta ([University of Missouri--Columbia], 2014)
    We construct a family of algebraic discrete rank 1 valuations whose associated Hilbert function cannot be written as the sum of a quasi-polynomial and a bounded function. We further show that the set of multiplicities ...
  • Lorentzian warped products and static space-times 

    Allison, Dean Edwin (University of Missouri--Columbia, 1985)
  • A vector treatment of the projective properties of plane curves 

    Canaday, Ernest Franklin (University of Missouri, 1916)
  • Limit of many molecules dynamics with rigorous macroscopic results 

    Jacob, Nicholas C. (University of Missouri--Columbia, 2013)
    The thesis builds on recent ideas that combine work by C.B. Morrey (1955) and D.W. Jepsen & D. ter Haar (1962) with more recent analytic techniques: measure disintegration, PDEs for measures, etc. (M.I. Vishik & A.V. ...
  • Stability estimates for semigroups and partly parabolic reaction diffusion equations 

    Yurov, Valerian (University of Missouri--Columbia, 2013)
    The purpose of my dissertation is the application of the methods of abstract theory of strongly continuous operator semigroups (and of evolution semigroups in particular) to study of the spectral properties of a class of ...
  • Frames and projections 

    Cahill, Jameson (University of Missouri--Columbia, 2013)
    In this dissertation we explore several ways in which the concept of projections arise infinite frame theory. In the first chapter we show that the Paulsen problem from frame theory is equivalent to a long standing open ...
  • Groupoids and semigroupoids 

    Vasko, Maria (University of Missouri--Columbia, 2013)
    The theory of semigroupoids and groupoids makes the transition between arbitrary sets and groups. The usefulness of developing theory stems from various applications where a group structure is lacking, yet there exists ...
  • Stochastically perturbed Navier-Stokes system on the rotating sphere 

    Varner, Gregory Alan (University of Missouri--Columbia, 2013)
    We show the existence and uniqueness of an invariant measure for the kick-forced Navier-Stokes system on the 2-dimensional sphere, first without deterministic force and then with a time-independent deterministic force. The ...
  • Fusion frame constructions and frame partitions 

    Peterson, Jesse D. (University of Missouri--Columbia, 2013)
    Fusion frames consist of a sequence of subspaces from a Hilbert space and corresponding positive weights so that the sum of weighted orthogonal projections onto these subspaces is an invertible operator on the space. Despite ...
  • On projective morphisms of varieties with nef anticanonical divisor 

    Ao, Lunhao (University of Missouri--Columbia, 2012)
    We shall study and discuss some important properties of the projective varieties with nef anticanonical bundles and nef tangent bundles. And we shall review some background and history about the subject. Then we shall use ...
  • Constant proportion portfolio insurance and related topics with empirical study 

    Wang, Mingming (University of Missouri--Columbia, 2012)
    The concept of Constant Proportion Portfolio Insurance (CPPI) in terms of jump-diffusion, as well as the associated mean-variance hedging problem, has been studied. Three types of risk related to: the probability of loss, ...
  • Topics in harmonic analysis and partial differential equations: extension theorems and geometric maximum principles 

    Alvarado, Ryan (University of Missouri--Columbia, 2011)
    The present thesis consists of two main parts. In the first part, we prove that a function defined on a closed subset of a geometrically doubling quasi-metric space which satisfies a Hölder-type condition may be extended ...
  • Results in analytic and algebraic number theory 

    Yeager, Aaron (University of Missouri--Columbia, 2012)
    The thesis begins with proving some theorems about Gauss sums and Jacobi sums. Using theorems the first chapter ends with a proof that if p is a prime such that p ≡ 1 (mod 4), then there are integers a and b such that p ...
