# Seminar Archive - 2017

Our regular seminar program covers a broad range of topics from applied mathematics, pure mathematics and statistics. All staff and students are welcome. A complete list of past seminars can be accessed via the left-hand menu.

John Steel, Jonathan Kress and others - UNSW Sydney
Following the seminar by Jonathan Kress on 11th August, this seminar time is intended for  debate and discussion on assessment policy and practice in mathematics and statistics. Everyone welcome to...

Gaurav Dhariwal - University of York, UK
The talk will be divided in two parts: In the first part I will talk about deterministic and stochastic Navier-Stokes equations with a constraint on the L 2 energy of the solution. I will speak about...

Boris Lishak - Univesity of Sydney
There are exponentially many triangulations of a fixed manifold extremely distant from each other in some natural metric. I will discuss similar results for Riemannian structures. In order to prove...

Yoni Nazarathy - University of Queensland
Much of operations research has to do with constraints. You want to do your best, but need to operate within certain bounds. A key question in the field is: what choice to make so as to maximise...

Dr Daniel Mansfield - School of Mathematics and Statistics, UNSW SYDNEY
N.b. This seminar has been postponed to a date to be decided.   NUMBAS is a mathematics assessment tool created by the University of Newcastle (UK). This software boasts many features that are...

Rob J Hyndman - Monash University
Time series can often be naturally disaggregated in a hierarchical or grouped structure. For example, a manufacturing company can disaggregate total demand for their products by country of sale,...

Philip Hackney - Macquarie University
Operads, invented in the early seventies by J.P. May, are a convenient tool for describing a variety of algebraic situations arising in homotopy theory, and have proven to be useful in many other...

Alexander Fish - University of Sydney
We will show how polynomial walks can be used to establish a twisted recurrence for sets of positive density in $\mathbb{Z}^d$. In particular, we will demonstrate that if $Γ ≤ GL_d(\mathbb{Z})$ is...

Igor Shparlinski - UNSW
We outline some new bounds on bilinear sums with Kloosterman sums and also with some similar sums. In particular, these bounds improve some recent results of V. Blomer, E. Fouvry, E. Kowalski, Ph....

Jonathan Kress and others - UNSW Sydney
In the seminar on 18th August John Steele reviewed the current UNSW policy on assessment with much discussion. In this seminar lead by Jonathan Kress the discussion on assessment in mathematics and...
