*Jinghao Huang - University of New South Wales*

The study of operator Holder functions has a long history and plays an important role in the perturbation theory of linear operators on a Hilbert space. The starting point is the so-called Powers--...

*Dr. Spiridon Penev - UNSW Sydney*

I will present some of my recent research under the motto “`Think globally, fit locally".
I will mostly stress on applications in robust density estimation but will also indicate applications in...

*Benoît Pasquier - Department of Earth System Science of the University of California*

Steady-state systems of nonlinear partial differential equations (PDEs) are common in engineering and the biogeosciences. These systems are typically controlled by parameters that can be estimated...

*Christian Le Merdy - Laboratoire de Mathématiques, Université de Franche-comté, Besançon*

Let $T\colon L^p(\mathcal{M})\to L^p(\mathcal{N})$ be a bounded operator between two noncommutative $L^p$-spaces, $1< p<\infty$. We say that $T$ is $\ell^1$-bounded (resp. $\ell^1$-contractive...

*Prof Frédéric Richard - Aix-Marseille Université*

In this talk, I will review some statistical methods I developed for the analysis of the anisotropy orthe heterogeneity of image textures. I will present extended fractional Brownian field models...

*Wadim Zudilin - Radboud University Nijmegen*

Ramanujan's formulas for $1/\pi$ and their generalizations remain an amazing topic, with many mathematical challenges.Recently it was observed that the formulas possess spectacular `supercongruence'...

*Donna Salopek - School of Mathematics and Statistics, UNSW Sydney*

We need to have an open discussion about several issues with the types of assessments that we give to our students. With online solutions readily available and contract cheating in the news, we need...

*Sylvie Paycha - University of Potsdam, on leave from the University Clermont-Auvergne*

According to the principle of locality in physics, events taking place at different locations should behave independently, a feature expected to be reflected in the measurements. In quantum field ...

*Abhishek Bhardwaj - ANU*

Non-negative polynomials are fundamental objects of study in real algebraic geometry. Testing the non-negativity of polynomials is known to be NP hard. Because of this, one generally looks to...

*Ilknur Tulunay - UNSW School of Maths and Stats*

ST-metric, arising from relative entropy can be thought as the distance between two discrete curves in the unit interval. Any data set can also be viewed as a discrete curve and can be transformed...
