A characterisation of the lines external to a quadric cone in PG(3,q), q odd
No full textIn this article, the lines not meeting a quadric cone in PG(3, q) (q odd) are characterised by their intersection properties with points and planes.Susan G. Barwick, David K. Butle
Rebellion at Coranderrk
No full textMore than a century ago an Aboriginal community in Victoria campaigned for recognition of their right to occupy and control the small acreage they had farmed for 25 years. Others wanted to develop this tract. Government spokesmen denied that the occupants had inherited any rights to this land and declared that, anyway, they were not really Aborigines. This book is about the rebellion at Coranderrk Aboriginal Station between 1874 and 1886. It describes how Coranderrk families fought to keep their land. To explain why they fought I must begin with the years before, to show what this 'miserable spadeful of ground' meant to them, and how they came to be there. Finally, I sketch what ultimately happened. First published in 1998, 12 years after the death of its author Diane Barwick, Rebellion at Coranderrk was an attempt to rectify some of the injustices of the past two-hundred-plus years in Australia, and to prevent similar occurrences in the future. It remains acutely relevant

Quadrics & Quadrals, Combinatorics & Characterisations: a Survey of Subspaces
No full textResults which link two distinct branches of mathematics are oftentimes remarkable. In Projective Finite spaces, we are fortunate to often observe such links. For example, finite projective spaces, which are defined combinatorially, when of dimension n ≥ 3 are isomorphic to projective spaces defined over a field. In this way, an abstract definition is given an algebraic underpinning. In this thesis we survey results which characterise algebraic constructions – quadrics – in projective finite spaces using purely combinatorial terms. A quadric is the set of points satisfying a second order polynomial, and there are many combinatorial characterisations for quadrics. We further refine our survey by looking not at characterisations which describe quadrics directly, instead we seek those characterisations which identify subspaces that meet a quadric in a certain way. Perhaps unsurprisingly, there is not a way of uniquely describing every quadric using purely combinatorial methods. Perhaps surprisingly, there are few counterexamples (where “few” refers to two infinite families). Sets combinatorially indistinguishable from a quadric, such as the Suzuki-Tits Ovoids, are not completely understood, and provide an avenue for further research. Collectively, sets combinatorially indistinguishable from quadrics, along with the quadrics, are referred to as quadrals, a term coined in [14]. In this document we survey combinatorial characterisations of subspaces associated with quadrics in PG(n, q), the projective finite space of dimension n and order q. In particular, we focus on n = 3 and 4. Chapter 1 of this thesis is dedicated to the background information needed to begin the study of quadrals. We also present a few characterisations of quadrics as point sets. Point set characterisations are often used in the process of characterising subspaces associated with quadrals. We end the chapter by presenting a few of the early characterisations of subspaces. In Chapter 2, we begin our survey in earnest, examining existing results pertaining to the three dimensional quadrics. To begin, we present a proof typical in this area as means of demonstration for the commonly used techniques. We go on to present the many surveyed results for the irreducible three dimensional quadrics, before summarising all known characterisations in Table 2.1. Lastly we present the combinatorial properties of the three dimensional quadrics in Section 2.6. In Chapter 3, we prove new characterisations of the sets of planes which meet the 3-dimensional quadrics. Many of the characterisations are proved in two ways. Using purely combinatorial arguments and alternatively using dualisation arguments. In Chapter 4, we look at the four dimensional quadrics. There are few existing characterisations in PG(4, q) of the singular quadrics, so we focus on P4, the non-singular quadric in PG(4, q). We present some of the combinatorial properties of P4 in Section 4.2. Again, we summarise the surveyed results in Table 4.6. We finish the chapter by providing several conjectures for further study using the tables in Section 4.2 and Table 4.6 as well as proving a new characterisation for the generator lines of P4. Lastly, in Chapter 5, we survey results applicable in PG(n, q) for n ≥ 4. We also present a new interesting corollary of a recent result, currently under review. Lastly, we prove two new characterisations using a dualisation argument, and provide commentary on direction for future research.Thesis (MPhil) -- University of Adelaide, School of Computer and Mathematical Sciences, 202
