Seminar Archive - 2020

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.

Alexander Gorodnik - University of Zurich
The spectral gap is an analytic property of group actions which can be described as absence of "almost invariant vectors" or more quantitatively in terms of norm bounds for suitable averaging...

Becky Armstrong - University of Victoria, Wellington
C*-algebras were first introduced in order to model physical observables in quantum mechanics, but are now studied more abstractly in pure mathematics. Much of the current research of C*-algebraists...

Nathan Jackson, Jan Zika and Jonathan Kress - UNSW SYDNEY
Nathan Jackson and Jan Zika will speak on their experiences with 1st and 2nd-year peer-review assessments.  Jonathan Kress will discuss future directions of peer-review assessments.   

Jörg Brüdern - University of Göttingen
We study arithmetic functions that are bounded in mean square, and simultaneously have a mean value over any arithmetic progression. A Besicovitch type norm makes the set of these functions a Banach...

Pavel Krivitsky - UNSW Sydney
 Dr Krivitsky will demonstrate how to set questions that require the students to write segments of R code, which are then automatically assessed by writing test cases, also in R. Rather than...

Feyisayo Olukoya (Shayo) - University of St Andrews, Scotland
We give a survey of recent results exploring connections between the Higman-Thompson groups and their automorphism groups and the group of automorphisms of the shift dynamical system. Our survey...

Simone Linz - University of Auckland
Recent advances in whole-genome studies provide increasingly strong evidence for a vital role of hybridization in the evolution of certain groups of species and allowing them to adapt to new...

Gal Binyamini - Weizmann Institute of Science
I will discuss "point counting" in two broad senses: counting the intersections between a trascendental variety and an algebraic one; and counting the number of algebraic points, as a function of...

Jackson Ryder - UNSW Sydney
Abelian categories are a generalisation of a module categories and play an important role in areas such as algebraic topology and algebraic geometry. A well-known result of Morita states that any...

Jens Marklof - University of Bristol
Take a point on the unit circle and rotate it N times by a fixed angle. The N points thus generated partition the circle into N intervals. A beautiful fact, first conjectured by Hugo Steinhaus in the...
