Groups and Combinatorics Seminar

Wei Jin (UWA)

will speak on

Finite s-Geodesic Transitive Graphs

at 1pm on Tuesday 20th of November in Maths Lecture Room 2

Abstract: A geodesic from a vertex u to a vertex v in a graph is one of the shortest paths from u to v, and this geodesic is called an s-geodesic if the distance between u and v is s.

A graph is said to be s-geodesic transitive if, for each i less than or equal to s, all i-geodesics are equivalent under the group of graph automorphisms. In this talk, I will show the relationship of 2-geodesic transitive graphs with a certain family of partial linear spaces. I will also compare s-geodesic transitivity of graphs with two other well-known transitivity properties, namely s-arc transitivity and s-distance transitivity.

This is a joint work with my supervisors.

All welcome

13:00 - SEMINAR - Groups and Combinatorics Seminar: Graphs and general preservers of zero products More Information
Groups and Combinatorics Seminar

Bojan Kuzma (University of Primorska, Slovenia)

will speak on

Graphs and general preservers of zero products

at 1pm on Tuesday 27th of November in MLR2

Abstract: We survey some results in preserver problems where graphs were used as the main tool. In particular, the classification of maps which preserve Jordan orthogonality (AB+BA=0) reduces to the fact that a certain graph is a core and has chromatic number 4. We also give a classification of certain matrices (rank-ones, semisimple, non-derogatory) in terms of a commuting graph.

All welcome.

Groups and Combinatorics Seminar

Neil Gillespie (UWA)

will speak on

Completely regular codes with large minimum distance

and

Daniel Hawtin (UWA) will speak on Elusive Codes in Hamming Graphs

at 1pm Tuesday 4th of December in MLR2



Abstracts:

Completely regular codes with large minimum distance: In 1973 Delsarte introduced completely regular codes as a generalisation of perfect codes. Not only are completely regular codes of interest to coding theorists due to their nice regularity properties, but they also characterise certain families of distance regular graphs. Although no complete classification of these codes is known, there have been several attempts to classify various subfamilies. For example, Borges, Rifa and Zinoviev classified all binary non-antipodal completely regular codes. Similarly, in joint work with Praeger, we characterised particular families of completely regular codes by their length and minimum distance, and additionally with Giudici, we also classified a family of completely transitive codes, which are necessarily completely regular. In this work with Praeger, and also with Giudici, the classification given by Borges, Rifa and Zinoviev was critical to the final result. However, recently Rifa and Zinoviev constructed an infinite family of non-antipodal completely regular codes that does not appear in their classification. This, in particular, led to a degree of uncertainty about the results with Praeger and with Giudici. In this talk I demonstrate how I overcame this uncertainty by classifying all binary completely regular codes of length m and minimum distance $ elta$ such that $ elta>m/2$.

Elusive Codes in Hamming Graphs:

We consider a code to be a subset of the vertex set of a Hamming graph. We examine elusive pairs, code-group pairs where the code is not determined by knowledge of its set of neighbours. We provide an infinite family of elusive pairs, where the group in question acts transitively on the set of neighbours of the code. In our examples, we find that the alphabet size always divides the length of the code, and prove that there is no elusive pair for the smallest set of parameters for which this is not the case.

15:00 - SEMINAR - Groups and Combinatorics Seminar, The Wall and Guralnick conjectures: history and legacy More Information
Abstract:

In 1961 G.E. Wall conjectured that the number of maximal subgroups of a finite group is less than the order of the group. The conjecture holds for all finite solvable groups (proved by Wall himself in his original paper) and holds for almost all finite simple groups, possibly all of them (proved by Liebeck, Pyber and Shalev in 2007). It is now known to be false in general, at least as originally stated, with infinitely many negative composite group examples found through a combination of computational and theoretical techniques. (I cite in particular computer calculations of Frank Luebeck, as partly inspired and later confirmed by calculations of my undergraduate student, Tim Sprowl, with theoretical input from myself and Bob Guralnick.) In this talk I will try to discuss the ingredients in this quite remarkable story, and I will mention as much of the legacy of positive consequences as time permits.

10:00 - EVENT - UWA Historical Society March 4th Convocation Centenary: Photo Shoot at 10am : All welcome on the steps of the old St George's Hall 500 Hay St Perth to celebrate 100 years to the day of the first meeting of UWA's Convocation. Website | More Information
You are invited to join us mark the 100th anniversary of the first meeting of the University of Western Australia’s Convocation.

The First meeting was held on March 4th 1913 in St George’s Hall, Hay St near the corner of Irwin Street. The historic façade including the portico, steps and tall white columns were restored when the new Perth District Court was constructed behind it at 500 Hay Street. To celebrate the Centenary of this meeting, a photo-shoot of 100 'graduates' will take place on the steps of the façade at 10am on Monday March 4th 2013.

The UWA Historical Society would be delighted if you could join us.

If you have academic robes, please bring them. If not please come anyway, as having just a few robed members will provide the ‘flavour’. Balloons for a joint release will be provided.

Monday March 4th is a public Holiday (Labour Day). There should be nearby street parking available and there is a public parking station across the road at King’s Hotel.

The UWA Centum will be there

15:00 - SEMINAR - Groups and Combinatorics Seminar, Generalised n-gons and the Feit-Higman theorem More Information
Name: Jon Xu (University of Melbourne/University of Western Australia)

will speak on

Generalised n-gons and the Feit-Higman theorem

at 3pm on Friday 8th of March.

Abstract:

Jacques Tits' theory of buildings played a vital role in the proof of the classification theorem on finite simple groups. The class of rank 2 buildings are also known as generalised n-gons.

In my talk, generalised n-gons will be defined as a certain class of bipartite graphs, so as to skip the (rather abstruse) building-theoretic definition. I will also state and outline a proof of the Feit-Higman theorem, which states that the majority of generalised n-gons can only exist for certain n. The proof, due to Kilmoyer and Solomon (1973), weaves together representation theory and graph theory.

To finish off, I will talk a little about what I've been doing here at UWA.
Thursday 14
16:00 - SEMINAR - Improving water quality through improved prediction : SESE Seminar More Information
Water quality and aquatic ecology models are widely used to facilitate management and scientific understanding of catchments, lakes, wetlands, rivers, estuaries and marine systems. But how good are these models? In recent years, numerous authors have argued that they have failed to keep up with advances in scientific understanding, remain highly disciplinary, and fail to adequately assess or reign in uncertainty. Here I will discuss current research trends and outline the need for new approaches able to deal with complexity, non-stationarity and uncertainty in future scenarios. Emerging data streams from new monitoring technologies, improved processing of existing sources such as satellite observations, citizen science initiatives, open-access monitoring data initiatives and real-time data portals all hold the potential to improve the way we run and assess environmental models. But the question remains: how can these diverse datasets be brought together in way that allows us to advance model accuracy and more constructively inform management?
Friday 15
15:00 - SEMINAR - Groups and Combinatorics Seminar, Erdös-Ko-Rado sets in finite classical polar spaces More Information
Abstract:

Erdös-Ko-Rado sets (EKR sets) are a family of k-sets of { 1, ..., n } that pairwise intersect in at least one element and were first studied by Erdös, Ko, and Rado in 1961. There are several generalizations of EKR sets. The speaker's main interest is study of EKR sets in polar spaces. These are sets of generators (maximal totally isotropic subspaces) that pairwise intersect in at least a point and were recently studied by Valentina Pepe, Leo Storme, and Frédéric Vanhove. After introducing EKR sets for sets, projective spaces, and polar spaces, some specific results using algebraic as well as geometric techniques will be presented.
