An Algebraic Approach to Voting Theory

Daugherty, Zajj 01 May 2005 (has links)
In voting theory, simple questions can lead to convoluted and sometimes paradoxical results. Recently, mathematician Donald Saari used geometric insights to study various voting methods. He argued that a particular positional voting method (namely that proposed by Borda) minimizes the frequency of paradoxes. We present an approach to similar ideas which draw from group theory and algebra. In particular, we employ tools from representation theory on the symmetric group to elicit some of the natural behaviors of voting profiles. We also make generalizations to similar results for partially ranked data.

The C+A theory of time: explaining the difference between the experience of time and the understanding of time.

Turner, Andrew J. January 2007 (has links)
The central problem addressed by this thesis is to attempt and reconcile our experience of time with our scientific understanding of time. Science tells us that time is static yet we experience it as dynamic. In the literature there tend to be two positions. Those who follow the science and claim that time is static and that our experience is mind-independent; those who favour our experience and question the science. I attempt to reconcile these positions. To do this I adopt terminology set out by McTaggart (1908) who termed the static view the B series and the dynamic view the A series. The literature that has developed out of this breaks down into the A Theory where time is the past, present and future; and the B Theory, where time is just involves events being earlier than or later than other events. I reject both positions as accounts of ontology. I adopt McTaggart’s C series, a series of betweenness only, on the grounds that it is this series that is mostly aligned to science. Given the C series, our experience requires explanation. A claim of mind-dependency is insufficient. I argue that the A series really refers to mind-dependent features that are brought out by our interaction with the C series; much like the way that colour is brought out by our interaction with a colourless world. The B series is the best description of the contents of time, not time itself. To examine the experience of time I adopt phenomenology to describe that experience. From within experience I show that certain features of that experience cannot be attributed to a mind-independent reality and use this as further evidence for the above claims. Finally I suggest that most theories of time are driven by the view that a theory of time has to be consistent. I examine recent developments in logic to see whether such a consistent requirement is needed. I conclude that the most we can get out of paraconsistent approaches is inconsistent experiences, not inconsistent reality. I conclude that the A series is the best description of our experience of time, the C series the best description of the ontology of time, and the B series as the best description of the contents of time. This reconciles our experience with our understanding of time. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1286776 / Thesis(PhD)-- School of Humanities, 2007

On 1-factorizations of the complete graph and the relationship to round robin schedules

Gelling, Eric Neil 10 June 2016 (has links)
The following new results concerning 1-factorizations of the complete graph are proved: (1) There are exactly 6 equivalence classes of 1-factorizations of the complete graph with 8 vertices. (2). There are exactly 396 equivalence classes of 1-factorizations of the complete graph with 10 vertices. Representatives of each of the equivalence classes are presented. The size of the automorphism group of each equivalence class of 1-factorizations of the complete graph with 2n vertices for n ≤ 5 is also found. Several theorems and results related to 1-factorizations of the complete graph are presented, and the relationship to round robin schedules is shown. An application problem demonstrates the importance of the choice of the equivalence class of round robin schedules in the solvability of the problem. / Graduate
