What is the Geometric Langlands Conjecture about? How could you best exploit a stream of data flowing by too fast to capture? I think we mathematicians are provoked to ask such questions by our sense that underneath the vastness of mathematics is a fundamental unity allowing us to look into many different corners -- though we couldn't possibly work in all of them.

Many of you will recall the AWM 40th Anniversary conference held in 2011 at Brown University. The enthusiasm generat- The purpose of the Association ed by that conference gave rise to a plan to hold a series of biennial AWM Research for Women in Mathematics is Symposia around the country. The first of these, the AWM Research Symposium 2013, took place this weekend on the beautiful Santa Clara University campus. • to encourage women and girls to study and to have active careers The symposium attracted close to 150 participants. The program included 3 plenary in the mathematical sciences, and talks, 10 special sessions on a wide variety of topics, a contributed paper session, • to promote equal opportunity and poster sessions, a panel, and a banquet. The Santa Clara campus was in full bloom the equal treatment of women and and the weather was spectacular. Thankfully, the poster sessions and coffee breaks girls in the mathematical sciences. were held outside in a courtyard or those of us from more frigid climates might have been tempted to play hooky! The event opened with a plenary talk by Maryam Mirzakhani. Mirzakhani is a professor at Stanford and the recipient of multiple awards including the 2013 Ruth Lyttle Satter Prize. Her talk was entitled “On Random Hyperbolic Manifolds of Large Genus.” She began by describing how to associate a hyperbolic surface to a graph, then proceeded with a fascinating discussion of the metric properties of surfaces associated to random graphs. -
What Are Lyapunov Exponents, and Why Are They Interesting?
BULLETIN (New Series) OF THE AMERICAN MATHEMATICAL SOCIETY Volume 54, Number 1, January 2017, Pages 79–105 http://dx.doi.org/10.1090/bull/1552 Article electronically published on September 6, 2016 WHAT ARE LYAPUNOV EXPONENTS, AND WHY ARE THEY INTERESTING? AMIE WILKINSON Introduction At the 2014 International Congress of Mathematicians in Seoul, South Korea, Franco-Brazilian mathematician Artur Avila was awarded the Fields Medal for “his profound contributions to dynamical systems theory, which have changed the face of the field, using the powerful idea of renormalization as a unifying principle.”1 Although it is not explicitly mentioned in this citation, there is a second unify- ing concept in Avila’s work that is closely tied with renormalization: Lyapunov (or characteristic) exponents. Lyapunov exponents play a key role in three areas of Avila’s research: smooth ergodic theory, billiards and translation surfaces, and the spectral theory of 1-dimensional Schr¨odinger operators. Here we take the op- portunity to explore these areas and reveal some underlying themes connecting exponents, chaotic dynamics and renormalization. But first, what are Lyapunov exponents? Let’s begin by viewing them in one of their natural habitats: the iterated barycentric subdivision of a triangle. When the midpoint of each side of a triangle is connected to its opposite vertex by a line segment, the three resulting segments meet in a point in the interior of the triangle. The barycentric subdivision of a triangle is the collection of 6 smaller triangles determined by these segments and the edges of the original triangle: Figure 1. Barycentric subdivision.

Stable Accessibility Is C1 Dense
Stable accessibility is C1 dense Dmitry Dolgopyat and Amie Wilkinson August 27, 2003 Abstract We prove that in the space of all C r (r ≥ 1) partially hyperbolic diffeomorphisms, there is a C 1 open and dense set of accessible dif- feomorphisms. This settles the C 1 case of a conjecture of Pugh and Shub. The same result holds in the space of volume preserving or symplectic partially hyperbolic diffeomorphisms. Combining this theorem with results in [Br], [Ar] and [PugSh3], we obtain several corollaries. The first states that in the space of volume preserving or symplectic partially hyperbolic diffeomorphisms, topological transitivity holds on an open and dense set. Further, on a symplectic n-manifold (n ≤ 4) the C 1-closure of the stably transitive symplectomorphisms is precisely the closure of the partially hyperbolic symplectomorphisms. Finally, stable ergodicity is C 1 open and dense among the volume preserving, partially hyperbolic diffeomorphisms satisfying the additional technical hypotheses of [PugSh3] . Introduction This paper is about the accessibility property of partially hyperbolic diffeo- morphisms. We show that accessibility holds for a C1 open and dense set in the space of all partially hyperbolic diffeomorphisms, thus settling the C1 version of a conjecture of Pugh and Shub [PugSh1]. Partially hyper- bolic diffeomorphisms are similar to Anosov diffeomorphisms, in that they possess invariant hyperbolic directions, but unlike Anosov diffeomorphisms, they can also possess invariant directions of non-hyperbolic behavior. Ac- cessibility means that the hyperbolic directions fill up the manifold on a macroscopic scale. Accessibility often provides enough hyperbolicity for a 1 variety of chaotic properties, such as topological transitivity [Br] and ergod- icity [PugSh3], to hold. -

Obituary Notices Ronald Drayton Brown
Obituary notices Ronald Drayton Brown Died 31 October 2008, elected to Fellowship 1965 Ronald Drayton (Ron) Brown was born in Melbourne on 14 October 1927. He grew up as an only child in modest suburban circumstances in Prahran and did not come from a scientific or academic background. His father had achieved some distinction in amateur athletics. His secondary education was at Wesley College, to which he had won a scholarship. He excelled in mathematics and physics and was an interested reader of astronomy books. He was dux of the school in his final year and was awarded an exhibition in physics in the Victorian matriculation examinations. In his first undergraduate year at the University of Melbourne, he majored in physics and chemistry. In second year he dropped Ron Brown physics, despite scoring better results than in chemistry. While completing a chemistry major he also informally attended the lectures in third year physics and mathematics, without completing the examinations, ending up with an effective triple major for his BSc in 1946. In the days before it was possible to do a PhD anywhere in Australia, Ron began his research career as an MSc student in the Department of Chemistry at the University of Melbourne with Dr Francis Lahey as supervisor. His thesis topic was alkaloid products from Australian plants, particularly Acronychia baueri. He had chosen this project because it would involve some organic chemistry and some spectroscopy. He was attracted by the relationships between the structure of organic compounds and their spectra, and the use of these ideas in deducing the structure of newly isolated compounds. -

Carbon fibre is a low weight product with high rigidity, tensile strength and chemical resistance that is used in aerospace, civil engineering, cars, health and the military. Successful collaborations like this demonstrate how the Australian research sector can accelerate research, lead innovation and expand job opportunities in the country. About this report This annual report is a summary of CSIRO’s activities and financial position for the 12-month period ended 30 June 2017. In this report, unless otherwise stated, references to the ‘organisation’, ‘we’, ‘us’ and ‘our’ refer to CSIRO as a whole. In this report, references to a year are to the financial year ended 30 June 2017, unless otherwise stated. It is also available at: www.csiro.au/annualreport2017. COVER: Nanomaterials, like the carbon nanotubes illustrustrated on the front cover, are extremely small chemicals, millionths of a millimetre in size. They come in many forms each with unique mechanical, electronic and optical properties. Through the development of new products and processes, nanotechnology will potentially contribute solutions to major challenges facing Australia in the electronic, energy and environmental sectors.

Bibliometrics in the Context of the UK Research Assessment Exercise Bernard W
Statistical Science 2009, Vol. 24, No. 1, 15–16 DOI: 10.1214/09-STS285A Main article DOI: 10.1214/09-STS285 © Institute of Mathematical Statistics, 2009 Comment: Bibliometrics in the Context of the UK Research Assessment Exercise Bernard W. Silverman Abstract. Research funding and reputation in the UK have, for over two decades, been increasingly dependent on a regular peer-review of all UK de- partments. This is to move to a system more based on bibliometrics.
