Categories Of Fuzzy Sets With Values In A Quantale Or Projectale, Lawrence Stout Jan 1995

Categories Of Fuzzy Sets With Values In A Quantale Or Projectale, Lawrence Stout

Lawrence N. Stout

Properties of the lattice L are reflected in the properties of the categories Set(L), Set(L)/(A,α), and the lattice U(A, α). The lattices U(A,α) best reflect the structures on the lattice if the structure is inherited by closed down segments and direct products. Operations at the level of the slice categories require distributivity too. The first object of this paper is to see how the additional structures given by an associative operation & which distributes over sups and hence has a right adjoint (a quantale in the sense of Rosenthal [7]) shows up at the three different levels for fuzzy sets. …


A Completely Integrable System And Parametric Representation Of Solutions Of The Wadati-Konno-Ichikawa Hierarchy, Zhijun Qiao Jan 1995

A Completely Integrable System And Parametric Representation Of Solutions Of The Wadati-Konno-Ichikawa Hierarchy, Zhijun Qiao

School of Mathematical and Statistical Sciences Faculty Publications and Presentations

A finite-dimensional involutive system is presented, and the Wadati-Konno- Ichikawa (WKI) hierarchy of nonlinear evolution equations and their commutator representations are discussed in this article. By this finite-dimensional involutive system, it is proven that under the so-called Bargmann constraint between the potentials and the eigenfunctions, the eigenvalue problem (called the WKI eigenvalue problem) studied by Wadati, Konno, and Ichikawa [J. Phys. Sot. Jpn. 47, 1698 (1979)] is nonlinearized as a completely integrable Hamiltonian system in the Liouville sense. Moreover, the parametric representation of the solution of each equation in the WKI hierarchy is obtained by making use of the solution …


Periodicity And Indecomposability, William Thomas Ingram Jan 1995

Periodicity And Indecomposability, William Thomas Ingram

Mathematics and Statistics Faculty Research & Creative Works

In this paper we characterize the existence of periodic points of odd period greater than one for unimodal mappings of an interval onto itself. The interesting juxtaposition of this condition with the occurrence in inverse limits of the well-known Brouwer-Janiszewski-Knaster continuum is explored. Also obtained is a characterization of indecomposability of certain inverse limits using a single unimodal bonding map. © 1995 American Mathematical Society.


Introduction To Linear Algebra: Models, Methods, And Theory, Alan Tucker Jan 1995

Introduction To Linear Algebra: Models, Methods, And Theory, Alan Tucker

Department of Applied Mathematics & Statistics Faculty Books

This book develops linear algebra around matrices. Vector spaces in the abstract are not considered, only vector spaces associated with matrices. This book puts problem solving and an intuitive treatment of theory first, with a proof-oriented approach intended to come in a second course, the same way that calculus is taught. The book's organization is straightforward: Chapter 1 has introductory linear models; Chapter 2 has the basics of matrix algebra; Chapter 3 develops different ways to solve a system of equations; Chapter 4 has applications, and Chapter 5 has vector-space theory associated with matrices and related topics such as pseudoinverses …


Numeric Transmission/Cultural Transition, Paul B. Pekarek Jan 1995

Numeric Transmission/Cultural Transition, Paul B. Pekarek

Honors Theses, 1963-2015

This thesis is a study of the computational methods and common use of mathematics during the Middle Ages. It also discusses the cultural transition that was associated with the numeric transition from the Roman numeral system to the Hindu-Arabic numeral system and the numeric systems' corresponding calculation methods in Christian Europe during the late Middle Ages and early Renaissance. I claim that the transition from Roman numerals to Hindu-Arabic numerals was a result of cultural influences. Furthermore, I show that the transition was steady and found its basis in preexisting forms of calculation. I also look at the influences that …


The Genus 22 Crossing Number Of K9, Adrian Riskin Jan 1995

The Genus 22 Crossing Number Of K9, Adrian Riskin

Mathematics

Our main result is that a 1971 conjecture due to Paul Kainen is false. Kainen's conjecture implies that the genus 2 crossing number of K 9 is 3. We disprove the conjecture by showing that the actual value is 4. The method used is a new one in the study of crossing numbers, involving proof of the impossibility of certain genus 2 embeddings of Ks.


Computations For A Vibrating System Diagonalize The Variance, J. N. Boyd, P. N. Raychowdhury Jan 1995

Computations For A Vibrating System Diagonalize The Variance, J. N. Boyd, P. N. Raychowdhury

Mathematics and Applied Mathematics Publications

The transformations to diagonalize potential energy matrices for coupled harmonic oscillators will also diagonalize the variance when written in matrix form. After a brief review of a geometrical interpretation of the variance, the transformations are described and an example is given.


Conjugacy Classes Of Triple Products In Finite Groups, Kevin Hutson, Emily Salvo Jan 1995

Conjugacy Classes Of Triple Products In Finite Groups, Kevin Hutson, Emily Salvo

Mathematical Sciences Technical Reports (MSTR)

For an underlying finite group G, we establish estimates on the number of triples that bind a certain set to one conjugacy class, or else breaks it into two conjugacy classes.


Point-Valued Mappings Of Sets, Matt Insall Jan 1995

Point-Valued Mappings Of Sets, Matt Insall

Mathematics and Statistics Faculty Research & Creative Works

Let X be a metric space and let CB(X) denote the closed bounded subsets of X with the Hausdorff metric. Given a complete subspace Y of CB(X), two fixed point theorems, analogues of results in [1], are proved, and examples are given to suggest their applicability in practice.


Brain State In A Convex Body, S. Hui, Martin Bohner Jan 1995

Brain State In A Convex Body, S. Hui, Martin Bohner

Mathematics and Statistics Faculty Research & Creative Works

We study a generalization of the brain-state-in-a-box (BSB) model for a class of nonlinear discrete dynamical systems where we allow the states of the system to lie in an arbitrary convex body. The states of the classical BSB model are restricted to lie in a hypercube. Characterizations of equilibrium points of the system are given using the support function of a convex body. Also, sufficient conditions for a point to be a stable equilibrium point are investigated. Finally, we study the system in polytopes. The results in this special case are more precise and have simpler forms than the corresponding …

Historical Development Of The Newton-Raphson Method, Tjalling Ypma Jan 1995

Historical Development Of The Newton-Raphson Method, Tjalling Ypma

Mathematics Faculty Publications

This expository paper traces the development of the Newton-Raphson method for solving nonlinear algebraic equations through the extant notes, letters, and publications of Isaac Newton, Joseph Raphson, and Thomas Simpson. It is shown how Newton's formulation differed from the iterative process of Raphson, and that Simpson was the first to give a general formulation, in terms of fluxional calculus, applicable to nonpolynomial equations. Simpson's extension of the method to systems of equations is exhibited.


A Sturm Separation Theorem For A Linear 2nth Order Self-Adjoint Differential Equation, Charles T. Fulton, Wu Limin, Steven Pruess Jan 1995

A Sturm Separation Theorem For A Linear 2nth Order Self-Adjoint Differential Equation, Charles T. Fulton, Wu Limin, Steven Pruess

Mathematics and System Engineering Faculty Publications

For the 2nth order equation, (−1)nv(2n)+qv=0, with q continuous, we obtain a Sturm Separation theorem, involving n+1 solutions of the equation, which is somewhat analogous to the classical result that the zeros of two linearly independent solutions of the second order equation separate each other.


Partial Least-Squares: Theoretical Issues And Engineering Applications In Signal Processing, Fredric M. Ham, Ivica Kostanic Jan 1995

Partial Least-Squares: Theoretical Issues And Engineering Applications In Signal Processing, Fredric M. Ham, Ivica Kostanic

Mathematics and System Engineering Faculty Publications

In this paper we present partial least-squares (PLS), which is a statistical modeling method used extensively in analytical chemistry for quantitatively analyzing spectroscopic data. Comparisons are made between classical least-squares (CLS) and PLS to show how PLS can be used in certain engineering signal processing applications. Moreover, it is shown that in certain situations when there exists a linear relationship between the independent and dependent variables, PLS can yield better predictive performance than CLS when it is not desirable to use all of the empirical data to develop a calibration model used for prediction. Specifically, because PLS is a factor …
