*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,...
