Marija Cvetković - University of Niš, Serbia
Perov's theorem is one of many different extensions of the famous Banach fixed point theorem, one which is notable for its wide spectra of applications. It claims existence and uniqueness of a fixed...

Prof. Wolf-Juergen Beyn - Bielefeld University, Germany
Nonlinear eigenvalue problems are ubiquitous in the stability analysis of nonlinear systems, such as vibrating systems or systems with delay. Numerical discretizations then lead to large and sparse...

Emily Peters - Loyola University Chicago
Maybe you've heard of diagram algebras, planar algebras, "spiders" or something similar. And you're wondering, is this really math? Are the pictures an analogy or are they actual mathematical objects...

Min Sha - Macquarie University
We call non-zero complex numbers $z_1, \ldots, z_n$ multiplicatively dependent if there exist integers $k_1, \ldots, k_n$, not all zero, such that $z_1^{k_1} \cdots z_n^{k_n}=1$. The multiplicative...

Maike Massierer - UNSW
Schoof's algorithm is a standard method for counting points on elliptic curves defined over finite fields of large characteristic, and it was extended by Pila to higher-dimensional abelian varieties...

Prof Tak Kuen Siu - Macquarie University
In this talk, we shall discuss a self-exciting threshold jump-diffusion model for option valuation. This model incorporates regime switches without introducing an exogenous stochastic factor process...

Lia Vas - University of the Sciences, Philadelphia, USA
I have been working in algebra and ring theory, in particular with rings of operators, involutive rings, Baer *-rings and Leavitt path algebras. These rings were introduced in order to simplify the...

Travis Schramek - Scripps Institution of Oceanography (USA)
Observations from around the island group of Palau, located in the tropical Western Pacific, exhibit a persistent presence of baroclinic coastally trapped waves. The signals are found in records of...

Dr Jim Pettigrew - Mathematics Support Hub, Western Sydney University
In this talk I will outline (some) contemporary research tackling the questions of equity, access and disadvantage in mathematics education. I will also reflect on my experience in supporting the...

James H Albert - Bowling Green State University
Abstract: Baseball fans are fascinated with splits, where player offensive or defensive statistics are broken down by different situations, such as home/away, date, same side/opposite arm pitchers,...
