Actionable ThreeWay Decisions
Gao, Cong (Faculty of Graduate Studies and Research, University of Regina, 201809)In this thesis, we analyze both the trisecting and acting aspects of threeway decisions. In an evaluation based model of threeway decisions, there are two steps: trisecting and acting. The trisecting step constructs ... 
Calculating and Preserving Star Sets and Star Complements of General Matrices
Bergen, Ryan Paul (Faculty of Graduate Studies and Research, University of Regina, 20170818)This thesis presents several results relating to star sets and star complements of graphs. While a method for calculating star sets and star complements involving pro jection matrices has been known since their introduction, ... 
CameronLiebler Sets for 2Transitive Groups
Palmarin, Daniel Michael (Faculty of Graduate Studies and Research, University of Regina, 202011)This research was conducted on 2transitive groups whose minimal normal subgroup is abelian. Suppose G is such a group and ΓG is its derangement graph. Any maximum coclique S of ΓG has a characteristic vector xS. Each xS ... 
Complexity Parameters for Learning MultiLabel Concept Classes,
Samei, Rahim (Faculty of Graduate Studies and Research, University of Regina, 201503)In Computational Learning Theory, one way to model a concept is to consider it as a member of the Cartesian products of instances (sets), where each instance may correspond to a binary or multivalued domain. A concept ... 
Convergence and Comparison Theorems for Various Splittings of Matrices Based on Generalized Inverses
Agasthian, Vijayaparvathy (Faculty of Graduate Studies and Research, University of Regina, 201503)The convergence of iterative methods for numerically solving the linear systems of equations associated with different types of splittings has been well studied in the literature. In this dissertation, we define new types ... 
Dietary Niche and Foraging Ecology of a Generalist Predator, DoubleCrested Cormorant (Phalacrocorax Auritus): Insight Using Stable Isotopes
Doucette, Jennifer Lee (Faculty of Graduate Studies and Research, University of Regina, 201204)The ability of predator populations to expand their ranges and adapt to new environments is often attributed to having a generalist dietary strategy, which is thought to be represented both at the population and individual ... 
Distinguishing Linear Sets and Pattern Languages With Membership Examples
Gao, Ziyuan (Faculty of Graduate Studies and Research, University of Regina, 201709)In Computational Learning Theory, a binary concept is often represented by a set of pairs (x; l), where x varies over a set of instances known as a universe or instance space, and l is a label, either "+" or "", indicating ... 
Eigenvalues of KUniform Hypergraphs
Gorr, Adam Vernon (Faculty of Graduate Studies and Research, University of Regina, 201708)We de ne two separate attempts to generalize the de nition of eigenvalues to hypergraphs and show several results related to each. The rst approach is rooted in 2dimensional matrices and allows for the generalization ... 
The ErdősKoRado Theorem for intersecting families of permutations.
Purdy, Alison May (Faculty of Graduate Studies and Research, University of Regina, 2010)The ErdősKoRado Theorem is a fundamental result in extremal set theory. It describes the size and structure of the largest collection of subsets of size k from a set of size n having the property that any two subsets ... 
The ErdősKoRado Theorem for Transitive Permutation Groups
Razafimahatratra, Andriaherimanana Sarobidy (Faculty of Graduate Studies and Research, University of Regina, 202203)Given a transitive permutation group \(G \le Sym(\Omega)\), a subset \(F\) of \(G\) is \(\textit {intersecting}\) if any two elements of \(F\) agree on some elements of \(\Omega\). We are interested in the problem of finding ... 
Extensions of the ErdősKoRado Theorem to Perfect Matchings
Nasrollahi Shirazi, Mahsa (Faculty of Graduate Studies and Research, University of Regina, 20220331)One of the important results in extremal set theory is the ErdősKoRado (EKR) theorem which gives a tight upper bound on the size of intersecting sets. The focus of this thesis is on extensions of the EKR theorem to ... 
Maximum Intersecting Families of Permutations
Ahmadi, Bahman (Faculty of Graduate Studies and Research, University of Regina, 201307)In extremal set theory, the Erd}osKoRado (EKR) theorem gives an upper bound on the size of intersecting ksubsets of the set {1; : : : ;n}. Furthemore, it classi es the maximumsized families of intersecting ksubsets. ... 
Measurement of the Beam Asymmetry for the ETA and ETA Prime Mesons with the Gluex Experiment
Beattie, Tegan Donald (Faculty of Graduate Studies and Research, University of Regina, 201905)The GlueX Experiment in Hall D at Jefferson Lab ultimately aims to provide evidence of hybrid mesons, quarkantiquark pairs with gluonic excitations, which are predicted by quantum chromodynamics calculations on the lattice. ...
