## Current short course listing

**WINTER 2017: CHEVALLEY GROUPS AND LIE ALGEBRAS WITH BUILT-IN STRUCTURE CONSTANTS
**

**Overview of course content**

The *structure constants* of a Lie algebra or Kac-Moody algebra g are the constants that occur in the evaluation of the Lie bracket in terms of a choice of basis for the Lie algebra. In the known methods for computing them, structure constants are determined only up to a sign due to the existence of a canonical central extension of the root lattice of the Lie algebra by a cyclic group of order two. Determining a consistent system of signs of structure constants is a persistent problem in computational Lie theory, computational number theory and their applications. In this short course, the basic structure theory of Lie algebras and Chevalley groups will be covered as needed. Some familiarity with finite dimensional Lie algebras is preferable though not required.

**SUMMER 2017: STOCHASTIC EQUATIONS AND PROCESSES IN PHYSICS AND BIOLOGY**

This course was delivered in February 2017.

**Overview of course content**

Fluctuations, noise and randomness determine basic properties of micro scale sized systems and are ubiquitous in nature. Our experience shows that if a classical system, no matter how large or small, is subjected to a process of a measurement, the outcome cannot be predicted with absolute certainty. Thus, the position of pollen grains, suspended in water, changes randomly in time as they jiggle due to Brownian motion; neural cells in any living organism generate a random series of electric pulses in response to the synaptic input from other cells; weather forecasts are unreliable because of the chaotic nature of global weather. In all these examples, the quantum effects can be neglected, and the origin of randomness is traced down to the complexity of the system or chaos. This course of lectures is designed to give an introduction into the phenomenological theory of stochastic equations and processes. The mathematical formalism of the stochastic calculus is explained using examples borrowed from physics and biology. The course is designed to be accessible for non-experts in the field.

##### Newcastle: Variational analysis and metric regularity theory

The University of Newcastle is offering a short course in the period 16 – 19 July 2013, entitled Variational analysis and metric regularity theory.

The course is open to postgraduate students, honours students and researchers who have access to Access Grid facilities.

If you are interested in participating, please register by sending an email to agr@amsi.org.au by 30 June with the following information: your full name, email address, University affiliation, and postal address.

**Overview of Course Content**

The classical regularity theory is centred around the implicit and Lyusternik-Graves theorems, on the one hand, and the Sard theorem and transversality theory, on the other. The theory (and a number of its applications to various problems of variational analysis) to be discussed in the course deals with similar problems for non-differentiable and set-valued mappings. This theory grew out of demands that came from needs of (mainly) optimization theory and subsequent understanding that some key ideas of the classical theory can be naturally expressed in purely metric terms without mention of any linear and/or differentiable structures.

**Topics to be covered**

The “theory” part of the course consists of five sections:

0. Classical theory;

1. Metric “phenomenological” theory;

2. Metric infinitesimal theory (with the concept of “slope” of DeGiorgi-Marino-Tosques at the

centre);

3. Banach theory (with subdifferentials and coderivatives as the main instrument of analysis);

4. Finite dimensional theory (mainly mappings with special structures, e.g. semi-algebraic, and non-smooth extensions of the Sard theorem and transversality theory).

In the second part of the course (some or all of) the following applications will be discussed:

5. Metric fixed point theory (with emphasis on two mappings models, e.g. F:X\to Y and G:Y\to X);

6. Subregularity, exact penalties and general approach to necessary optimality conditions (optimality

alternative);

7. Stability of solutions of systems of convex inequalities;

8. Curves of steepest descent for non-differentiable functions;

9. Von Neumann’s method of alternate projections for nonconvex sets;

10. Tame optimization and generically good behaviour;

11. Mathematical economics: extension of Debreu’s stability theorem for non-convex and non-smooth utilities.

Formally, for understanding of the course basic knowledge of functional analysis plus some acquaintance with convex analysis and nonlinear analysis in Banach spaces (e.g. Frechet and Gateaux derivatives, implicit function theorem) will be sufficient. Understanding of the interplay between analytic and geometric concepts would be very helpful.

##### Wollongong: Geometric Flows of Curves

The University of Wollongong is offering a short course in the period 15 – 25 July 2013, entitled Geometric Flows of Curves. The course is open to postgraduate students, honours students and researchers who have access to Access Grid facilities.

If you are interested in participating, please register by sending an email to agr@amsi.org.au by 15 June 2013 with the following information: your full name, email address, University affiliation, and postal address.

**Overview of Course Content**

Geometric flows of curves are families of curves varying smoothly with time according to a given law. One example of this is the curve shortening flow, a geometric evolution equation for curves where each point moves with velocity given by the curvature vector at that point. This evolution equation is the main focus of our study in this course. Our main goal is to give in detail the original argument of Gage-Hamilton establishing that convex initial curves shrink to smooth round points. This argument has by now been replaced by much more efficient methods. The original argument contains many standard tools, and so it is hoped that a presentation of this in detail will introduce students to valuable techniques and methods with application far beyond the realm of curve flows.

A secondary goal is to improve Gage-Hamilton’s Theorem to Grayson’s Theorem, the statement that all embedded initial curves shrink to points. The original proof for this will be discussed and summarised. Time permitting, we will also detail how some modern methods due to Huisken and Andrews-Bryan have shortened and replaced many of the steps from the original proofs of these theorems.

Exercises are given throughout and form a crucial part of the learning process.

**Topics to be covered**

1. Elementary geometry of curves

2. Short-time existence for general curve flows

3. The proof of Gage-Hamilton that convex initial curves shrink to round points under curve

shortening flow

4. A discussion of Grayson’s original proof

5. A discussion of the alternative proofs of Grayson’s theorem due to Huisken and Gage-Hamilton

The course does not have any formal prerequisites apart from calculus and differential equations.Some knowledge of calculus of variations, the geometry of curves, and PDEs, would be helpful, but is not required.

The course is targeted at Honours students, since some mathematical maturity is required and a little bit of discipline to engage in the exercises given during lectures. That said, students from any year are welcome to participate.

##### Summer 2012: A beginner’s course in finite volume approximation of scalar conservation laws

Monash University is offering a short course in the period 3 – 12 December 2012, entitled A beginner’s course in finite volume approximation of scalar conservation laws. Preliminary course information can be found below. The course is open to postgraduate students, honours students and researchers who have access to Access Grid facilities. If you are interested in participating, please register by sending an email to agr@amsi.org.au by Thursday 1 November with the following information: your full name, email address, University affiliation, and postal address.

**Overview of Course Content**

We will present and study some methods to discretise scalar conservation laws in 1D space dimension. Considering first the (apparently) simple linear case, we will raise a few of the stability issues that can arise when discretising these partial differential equations. We will then introduce schemes for non-linear equation, based on the notion of monotone discrete fluxes. Classical examples (Lax-Friedrichs, Godounov) of such fluxes will be given, and we will try to understand the concept of numerical diffusion arising in those schemes. Theoretical study will be performed: stability, discrete entropy inequalities, convergence in the BV case, convergence in the bounded case. The numerical diffusion introduced by monotone fluxes is a key element in the stability of the schemes, but it also leads to poor approximation of the shocks appearing in the solution. We will conclude the course by looking at some higher order methods (MUSCL techniques) which preserve stability while giving better qualitative approximations of shocks.
