Describing Quasi-Graphic Matroids, Nathan Bowler, Daryl Funk, Dan Slilaty 2020 Wright State University - Main Campus

Describing Quasi-Graphic Matroids, Nathan Bowler, Daryl Funk, Dan Slilaty

Mathematics and Statistics Faculty Publications

The class of quasi-graphic matroids recently introduced by Geelen, Gerards, and Whittle generalises each of the classes of frame matroids and liftedgraphic matroids introduced earlier by Zaslavsky. For each biased graph (G, B) Zaslavsky defined a unique lift matroid L(G, B) and a unique frame matroid F(G, B), each on ground set E(G). We show that in general there may be many quasi-graphic matroids on E(G) and describe them all: for each graph G and partition (B, L, F) of its cycles such that B satisfies the theta property and each cycle in L meets each ...


Mathematical Reasoning Writing And Proof, Version 3, Ted Sundstrom 2020 Grand Valley State University

Mathematical Reasoning Writing And Proof, Version 3, Ted Sundstrom

Open Textbooks

Mathematical Reasoning: Writing and Proof is a text for the first college mathematics course that introduces students to the processes of constructing and writing proofs and focuses on the formal development of mathematics. Version 3 of this book is almost identical to Version 2.1. The main change is that the preview activities in Version 2.1 have been renamed to beginning activities in Version 3. This was done to emphasize that these activities are meant to be completed before starting the rest of the section and are not just a short preview of what is to come in the ...


Symmetric Presentations And Related Topics, Mayra McGrath 2020 California State University, San Bernardino

Symmetric Presentations And Related Topics, Mayra Mcgrath

Electronic Theses, Projects, and Dissertations

In this thesis, we have investigated several permutation and monomialprogenitors for finite images. We have found original symmetric presen-tations for several important non-abelian simple groups, including lineargroups, unitary groups, alternating groups, and sporadic simple groups.We have found a number of finite images, including : L(2,41), PSL(2,11)×2, L(2,8), and L(2,19), as homomorphic images of the permutation progenitors. We have also found PGL(2,16) : 2 =Aut(PSL(2,16)) and PSL(2,16) as homomorphic images of monomial progenitors. We have performed manual double coset enumeration of finte images. In addition, we ...


The Impact Of Departmentalized And Traditional Instructional Settings On Economically Disadvantaged Fourth Grade Students' Mathematical Proficiency, Elizabeth Courtney Medlock 2020 Liberty University

The Impact Of Departmentalized And Traditional Instructional Settings On Economically Disadvantaged Fourth Grade Students' Mathematical Proficiency, Elizabeth Courtney Medlock

Doctoral Dissertations and Projects

All students must have opportunities to achieve high levels of mathematics learning, thus, organizational settings in the field of education should be carefully examined to determine the extent to which the instructional environment affects student achievement, growth, and application of grade level standards for students identified as economically disadvantaged. The purpose of this quantitative, causal-comparative study was to investigate differences in mathematical proficiency of economically disadvantaged fourth-grade students in departmentalized versus traditional instructional settings as measured by the 2019 Maryland PARCC mathematics assessment. A cluster sample of low-income fourth-grade students from 80 public elementary schools in a large, suburban school ...

Sensitivity Diagnostics And Adaptive Tuning Of The Multivariate Stochastic Volatility Model, Sebastian Baldivieso 2020 Portland State University

Sensitivity Diagnostics And Adaptive Tuning Of The Multivariate Stochastic Volatility Model, Sebastian Baldivieso

Dissertations and Theses

New methodologies for diagnostic analysis and adaptive tuning based on sensitivity information of the Multivariate Stochastic Volatility (MSV) model are established in this dissertation. The main focus is on obtaining optimal conditional volatilities from a time series set of financial data observed in the market by specifying a State-Space model with error covariance adaptive tuning of the MSV model. Variational Data Assimilation methods are used in this research as tools for obtaining the optimal a posteriori estimates of the multivariate series of volatilities. Calculus of Variations techniques are then applied to a forecast score function to derive the sensitivities of ...

Non-Associative Algebraic Structures In Knot Theory, Emanuele Zappala 2020 University of South Florida

Non-Associative Algebraic Structures In Knot Theory, Emanuele Zappala

Graduate Theses and Dissertations

In this dissertation we investigate self-distributive algebraic structures and their cohomologies, and study their relation to topological problems in knot theory. Self-distributivity is known to be a set-theoretic version of the Yang-Baxter equation (corresponding to Reidemeister move III) and is therefore suitable for producing invariants of knots and knotted surfaces. We explore three different instances of this situation. The main results of this dissertation can be, very concisely, described as follows. We introduce a cohomology theory of topological quandles and determine a class of topological quandles for which the cohomology can be computed, at least in principle, by means of ...


Random Models Of Idempotent Linear Maltsev Conditions. I. Idemprimality, Clifford Bergman, Agnes Szendrei 2020 Iowa State University

Random Models Of Idempotent Linear Maltsev Conditions. I. Idemprimality, Clifford Bergman, Agnes Szendrei

Mathematics Publications

We extend a well-known theorem of Murski\v{\i} to the probability space of finite models of a system M of identities of a strong idempotent linear Maltsev condition. We characterize the models of M in a way that can be easily turned into an algorithm for producing random finite models of M, and we prove that under mild restrictions on M, a random finite model of M is almost surely idemprimal. This implies that even if such an M is distinguishable from another idempotent linear Maltsev condition by a finite model A of M, a random search for a ...


Two- And Three-Loop Data For Groomed Jet Mass, Adam Kardos, Andrew J. Larkoski, Zoltán Trócsányi 2020 University of Debrecen

Two- And Three-Loop Data For Groomed Jet Mass, Adam Kardos, Andrew J. Larkoski, Zoltán Trócsányi

Portland Institute for Computational Science Publications

We discuss the status of resummation of large logarithmic contributions to groomed event shapes of hadronic final states in electron-positron annihilation. We identify the missing ingredients needed for next-to-next-to-next-to-leading logarithmic (NNNLL) resummation of the mMDT groomed jet mass in e+e collisions: the low-scale collinear-soft constants at two-loop accuracy, c(2)Sc, and the three-loop non-cusp anomalous dimension of the global soft function, γ(2)S. We present a method for extracting those constants using fixed-order codes: the EVENT2 program to obtain the color coefficients of c(2)Sc, and MCCSM for extracting γ(2)S. We present all necessary ...


Why Ellipsoids In Mechanical Analysis Of Wood Structures, F. Niklas Schietzold, Julio Urenda, Vladik Kreinovich, Wolfgang Graf, Michael Kaliske 2020 Technische Universitat Dresden

Why Ellipsoids In Mechanical Analysis Of Wood Structures, F. Niklas Schietzold, Julio Urenda, Vladik Kreinovich, Wolfgang Graf, Michael Kaliske

Departmental Technical Reports (CS)

Wood is a very mechanically anisotropic material. At each point on the wooden beam, both average values and fluctuations of the local mechanical properties corresponding to a certain direction depend, e.g., on whether this direction is longitudinal, radial or tangential with respect to the grain orientation of the original tree. This anisotropy can be described in geometric terms, if we select a point x and form iso-correlation surfaces -- i.e., surfaces formed by points y with the same level of correlation ρ(x,y) between local changes in the vicinities of the points x and y. Empirical analysis shows ...
