Our paper on fractals in r-tipping has been published today as Chaos 36, 083122 (2026) doi.org/10.1063/5.03... Many improvements over the pre-print, thanks to the very helpful comments by the editor and reviewers from Chaos @aip-publishing.bsky.social

Fractals in rate-induced tipping

When parameters of a dynamical system change sufficiently fast, critical transitions can take place even in the absence of bifurcations. This phenomenon is know

"Fractals in rate-induced tipping", new pre-print with Jason Qianchuan Wang and Yi Zheng. We show how fractal saddles in the phase space of non-linear dynamical systems lead to fractals in the parameter space controlling rate-induced tipping points. arxiv.org/abs/2601.16373

New preprint up, led by Joy (Qiping) Yang and Yash Pote, with Jonathan Scarlett: we consider a relaxation of the standard (distribution) closeness testing task, where the algo now only needs to distinguish between p=q (equal) and |H(p)-H(q)|=Ω(1) (their entropies differ). 📝 arxiv.org/abs/2605.23225

Entropy Equivalence Testing

We introduce the problem of \emph{entropy equivalence testing} for probability distributions, a relaxation of the well-studied closeness testing problem, where the distribution testing algorithm is no...

This is an important first step. Association with Horizon Europe would scale & diversify Australia international scientific collaborations We’ve long advocated for Association to Horizon Europe, recognising it would mitigate geopolitical risks & deliver economic & scientific benefits to Australia.

This chart shows the growth of Australia’s international science collaborations (measured by the number of co-authored publications) with various countries and regions from 2005 to 2024.
