    • Analytical and numerical methods for boundary value problems of mixed type 
      Kim, Young Sook (Texas A&M University. Libraries, 1990)
      Existence of a weak solution for some boundary value problems of mixed and hyperbolic types is proved by constructing multipliers which satisfy the multiplier inequalities. The nature of a singularity is then examined by ...
    • Best local approximation 
      Su, Lo-Yung (Texas A&M University. Libraries, 1979)
    • Centralizer near-rings on infinite groups 
      Zeller, Mike (Texas A&M University. Libraries, 1980)
      This work is a continuation of recent work done by Maxson and Smith on finite centralizer near-rings. Our attempt to generalize results which are known to hold for finite centralizer near-rings leads us naturally to a ...
    • Compactly supported wavelets with dilation factor a = 3 
      Lian, Jian-Ao (Texas A&M University. Libraries, 1993)
      It is well known that any compactly supported orthonormal (o.n.) wavelet which is symmetric or antisymmetric is some integer-translate and possible sign change of the Haar function. Here, the scaling factor a = 2 is used ...
    • Digraphs, automata and sandwich semigroups of binary relations 
      Chase, Karen Hafen (Texas A&M University. Libraries, 1978)
      This work is an outgrowth of recent work done investigating the transfer of information between automata and various semigroups associated with automata. Dennis Geller has introduced some relationships concerning automata ...
    • Extensions and applications of infinite dimensional Banach space theory 
      Farmer, Jeffrey Darrell (Texas A&M University. Libraries, 1992)
      We examine some connections between Banach space theory and other areas of functional analysis such as Lipschitz functions on metric spaces, operator theory and holomorphic function theory. We give an intrinsic characterization ...
    • A finite difference : boundary element scheme for solving parabolic boundary value problems and supercomputing 
      Chen, Chih-Hsuan (Texas A&M University. Libraries, 1994)
      The heat equation is a basic partial differential equation modelling heat conduction. Many numerical methods, such as finite-difference, finite-element, and boundary element methods, have been developed to solve the heat ...
    • Fixed points and the sequence of iterates 
      Singh, Kanhaya Lal (Texas A&M University. Libraries, 1980)
      In this work notions involving continuous mappings of metric and topological linear spaces are developed. It is shown that if C is a closed, bounded, convex subset o f a convex metric space and F : C - C is a commuting ...
    • Global existence and large time behavior of solutions to reaction-diffusion systems with large diffusion coefficients 
      Cupps, Brian Perry (Texas A&M University. Libraries, 1994)
      Systems of semilinear parabolic partial differential equations arise naturally in the modeling of certain reaction-diffusion processes. We consider m com ponent systems of the form ut = D A u + f( u ) on (r, T) x fl w ith ...
    • Hamiltonian cycles in bipartite plane cubic maps 
      Peterson, Douglas Lee (Texas A&M University. Libraries, 1977)
      The nature of bipartite cubic plane maps is investigated relative to questions concerning connectedness, local structure, and the line graph. Several contributions are made toward the solution of the conjecture of Barnette ...
    • Hankel approximation and its applications 
      Li, Xin (Texas A&M University. Libraries, 1991)
      General results in the theory of Hankel operators are described first. Hankel approximation in special situations is investigated from the geometric point of view, and the AAK theory on Hankel operators on the unit disc ...
    • Information-based complexity applied to numerical transport theory 
      Yu, Fan (Texas A&M University. Libraries, 1992)
      In this work, we apply a recently developed theory, information-based complexity, to numerical transport theory. Two classes of information, cell-average information and point-evaluation information, and two popular ...
    • The inverse electromagnetic scattering problem for a spatially homogeneous, dispersive and dissipative medium 
      Bui, Dat Duc (Texas A&M University. Libraries, 1993)
      The study of the inverse scattering problem for electromagnetic waves, especially under consideration of such realistic effects as spatial inhomogeniety, dispersion, dissipativity and multiple spatial dimensions, is based ...
    • Local mappings of operator algebras 
      Crist, Randall Lee (Texas A&M University. Libraries, 1993)
      Local derivations and automorphisms on operator algebras have been investigated in recent papers of Kadison, and Larson-Sourour. A local derivation η is a (norm continuous) linear map from an operator algebra A into an ...
    • Matrix methods, unbounded multipliers and summability of unbounded series 
      Kleiner, Alexander Francis (Texas A&M University. Libraries, 1969)
    • Mean interpolation and interpolation of entire functions 
      Shull, Carolyn Sue Flowers (Texas A&M University. Libraries, 1977)
      The purpose of this dissertation is two-fold. First a characterization of entire functions by a combination of the means of concentric circles and the derivatives at the center is given and a mean interpolation problem is ...
    • Norm closed bimodules of nest algebras 
      Dai, Xingde (Texas A&M University. Libraries, 1990)
      Let N be a complete nest in a separable Hilbert space H, and let algN be the nest algebra related to N. We obtain necessary and sufficient conditions for B(H) to be principally generated as a norm-closed bimodule of algN. ...
    • Normalization methods in the bootstrap central limit theorem 
      Sepanski, Steven J. (Texas A&M University. Libraries, 1991)
    • On certain classes of near-rings 
      Ligh, Steve Chong Hong (Texas A&M University. Libraries, 1969)
      Three special classes of near-rings are studied in this dissertation: near-fields, distributively generated near-rings, and near-rings with zero divisors. Chapter I contains introductory material. In Chapter II various ...
    • On polynomially bounded operators on Hilbert space 
      Gadidov, Radu Corneliu (Texas A&M University. Libraries, 1994)
      In this thesis we study properties of dual algebras generated by polynoniially bounded operators acting 011 a Hilbert space. We show that every absolutely continuous contraction in C(H) having an isometric H 00-functional ...
