  Gravitational and electrostatic potential fields and dynamics of non-spherical systems 

  Lam, Wai-Ting (2020-07)

  This thesis is devoted to several aspects of the n-body problem in the context of two models of interest: the gravitational n-body problem and the electrostatic n-body problem. In the case of gravitational n-body problem, ...
• Qualitative Properties for Positive Solutions of Nonlocal Equations 

  Hu, Yunyun (, 2020-05-28)

  This thesis is devoted to the study of properties for nonnegative solutions to nonlocal problems and integral equations. The main tools we use are the method of moving planes and the method of moving spheres.__________ ...
• Classical mechanics over fields of characteristic p greater than 0 

  Merewether, James William (ProQuest Dissertations & Theses, 1986)

  A formulation of the algebraic structures of a classical mechanics over fields of characteristic p {dollar}>{dollar} 0 is presented. It is shown how a definition of an abstract mechanics, which is a composition class of ...
• THE SCATTERING THEORY OF THE KLEIN-GORDON EQUATION IN TWO HILBERT SPACES WITH GENERAL AND OSCILLATING POTENTIALS 

  GELMAN, ALEXANDER (ProQuest Dissertations & Theses, 1984)

  This dissertation considers three problems associated with the Klein-Gordon Equation: (a) The conditions for the operator to be self-adjoint; (b) The existence of the wave operator; and (c) The completeness of the wave ...
• THE SPECTRA OF THE SCHROEDINGER OPERATOR 

  BRENNER, TERENCE (ProQuest Dissertations & Theses, 1984)

  We look at the Schrodinger operator H=-(DELTA)+q(x) where (DELTA) is the Laplacian and q(x)(epsilon)R('n). We give sufficient conditions for the spectrum of H to contain the interval of the form {lcub}a,(INFIN)) and ...
• EXISTENCE AND COMPLETENESS OF WAVE OPERATORS IN TWO HILBERT SPACES 

  ALTABET, MERYL J. (ProQuest Dissertations & Theses, 1984)

  In this thesis we consider an unperturbed self-adjoint operator H(,0) on a Hilbert space H(,0), the operators A, B mapping H(,0) to the Hilbert space K, and J a bounded linear operator mapping the Hilbert space H(,0) to ...
• DIFFERENCE EQUATION METHODS FOR SOLUTION OF PARTIAL DIFFERENTIAL EQUATIONS 

  KOHN, MERYLE CHERRICK (ProQuest Dissertations & Theses, 1982)

  Difference equation techniques are applied to determine sufficient conditions on polynomials P(x,y) for which the Fischer space related differential equation.;(DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI).;has (a) ...
• THE INVARIANCE PRINCIPLE AND ASYMPTOTIC COMPLETENESS FOR A QUANTUM MECHANICAL SYSTEM 

  HERZBERG, MARTIN (ProQuest Dissertations & Theses, 1982)

  We study operators H and H(,0) acting on the Hilbert Space L('2)(R). The free or unperturbed operator H(,0) is the multiplication (also known as the position) operator x. We consider H = H(,0) + A, where the perturbation ...
• TWO PARALLEL QUEUES CREATED BY ARRIVALS WITH TWO DEMANDS 

  HAHN, SUSAN ANN (ProQuest Dissertations & Theses, 1982)

  In this thesis we consider the system of two unbounded single server queues in which a customer upon arrival joins both queues. The arrivals are assumed to form a Poisson process with mean interarrival time 1 and the servers ...
• ERGODIC PROPERTIES OF A PARTICLE IN CONTACT WITH A HEAT BATH 

  RAVISHANKAR, KRISHNAMURTHI (ProQuest Dissertations & Theses, 1980)

  We study the ergodic properties of a system of point particles on the semi-infinite line. The particles evolve under a dynamics where the only interaction is between the first particle and each of the other particles through ...
• WISHART EXPECTATION OPERATORS AND INVARIANT DIFFERENTIAL OPERATORS 

  KUSHNER, HOWARD BURT (ProQuest Dissertations & Theses, 1980)

  Let E(,n) denote the expectation operator of the Wishart distribution W(k,n,(SUMM)) and let E(,n)('t) denote the "conditional" expectation operator defined by.;(DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI).;where ...
