Nonexistence of Solutions to Certain Families of Diophantine Equations
<p>In this work, I examine specific families of Diophantine equations and prove that they have no solutions in positive integers. The proofs use a combination of classical elementary arguments and powerful tools such as Diophantine approximations, Lehmer numbers, the modular approach, and earlier …

The Nonexistence of Shearlet-Like Scaling Multifunctions that Satisfy Certain Minimally Desirable Properties and Characterizations of the Reproducing Properties of the Integer Lattice Translations of a Countable Collection of Square Integrable Functions
… case. Two corollaries of these results are the nonexistence of composite scaling multifunctions of Haar-type, when the composite dilation group is infinite, and the nonexistence of classical multiwavelets, when the dilation matrix is integral and has determinant 1 in absolute value. </p> …

On moment conditions for the Girsanov Theorem
… of the Girsanov Theorem, we will show the nonexistence of an arbitrage in a market and will also explain a simplified version of Black-Scholes model.

Near-Group Categories
… given, in terms of G and k, for the existence or nonexistence of coherent associative structures for such fusion rules (ie, solutions to MacLane's pentagon equation). An explicit construction of matrix solutions to the pentagon equations is given for the cases where we establish existence, and …

Power Integral Points on Elliptic Curves
… equations, and utilizes them to display the nonexistence of perfect powers occurring in certain types of sequences. In particular we look at the denominator divisibility sequences (Bn) formed by Mordell elliptic curves ED : y2 = x3+D. For the curve-point pair (E−2, P), where E−2 : y2 = x3 −2, …

Detour : Los Angeles River Speed Cinema
… decelerating to a complete halt or even nonexistence is the modus operandi of late. Today's LA. is full of cars with no where to drive them really fast; brimmed with cinematic mementos but no real place to watch a film. It does not help that most of the architecture associated with …

A numerical framework for the direct simulation of solid-fluid systems
… dynamics has been severely limited by the nonexistence of a high-fidelity modeling capability for these multiphase systems. Continuum modeling approaches overlook the microscale solid-fluid interactions from which macroscopic system properties emerge, while experimental inquiries have been …

The impact of motivation on national employee performance in the United Nations Organizations: A case of the United Nations World Food Programme in Tanzania
… as, limited career development opportunities, nonexistence of loan & promotion, insufficient health benefits coverage, limited trainings and minimal salary increase in base pay. This study recommends that WFP should improve staff skills by strengthening capacity building considering …

Lifts of Frobenius on Arithmetic Jet Spaces of Schemes
… in geometry. As a final result, we prove the nonexistence of lifts of Frobenius on the first jet space of any smooth quadric hypersurface in projective space.

Optimal control problems on lie groups with symmetry breaking cost functions
… condition for optimality that relies on the nonexistence of conjugate points. Coordinate formulae are derived for computing conjugate points in the reduced Hamiltonian system, and we relate these conjugate points to local optimality in the original optimal control problem. These optimality …

Synthesis of Offset Dual Reflector Antennas Transforming a Given Feed Illumination Pattern Into a Specified Aperture Distribution
… slopes may vary too rapidly. In the event of nonexistence of a numerically rigorous smooth solution, an approximate solution that enforces the smoothness of the reflector surfaces can be obtained. In the approximate solution, the requirement for the aperture amplitude distribution is relaxed …

Guided modes and resonant transmission in periodic structures
… of guided modes, and prove the existence and nonexistence in structures in analogy to results for slabs. We provide a new existence result of nontrivial embedded guided modes, which are stable with respect to the wavenumber and nonrobust under perturbations of the structural geometry, in …

Critical behavior of the n-vector and charged n-vector models from an exact solution to the screening approximation
… results while for small n we explore the nonexistence of a solution in the regime of spatial dimension 2 < d < 4. Corrections to a previous publication are made. By keeping the dual leading corrections to the scaling Green's function we establish the correct connection between the Green's …

Nonlinear and Asymmetric Exchange Rate Pass-Through to Consumer Prices in South Africa
… lag (NARDL) model results reveal the nonexistence of a significant nonlinear asymmetric long-run correlation between exchange rate and consumer inflation. This is portrayed by the Wald test results, which suggest the absence of a nonlinear asymmetric correlation between inflation and …

The Structure of Models of Second-order Set Theories
… so that these embedding preserve the existence/nonexistence of upper bounds, at least for finite partial orders. Second I generalize some constructions of Marek and Mostowski from KM to weaker theories. They showed that every model of KM plus the Class Collection schema “unrolls” to a model of …

The culturally responsive teaching (CRT) scores were significantly higher than 3, implying that CRT was perceived to be implemented throughout the school community (p < 0.01). …
