~ Mahler Equations for Zeckendorf Numeration ~
Reem Yassawi treated us to a talk on her forthcoming paper Mahler Equations For Zeckendorf Numeration, co-authored with Olivier Carton. I'd not come across Zeckendorf's theorem which simply says that every positive integer can be represented uniquely as the sum of distinct non-consecutive Fibonacci numbers. To see that this 'amusement' is of some actual use was the first of several surprises in a talk that took care to carry the audience with it as it progressed. I loved how a function that was 'almost' linear was handled; there was a real sense of the small mathematical details being moulded into a malleable form such that they could be applied to tackle a significant, bigger problem. The photograph rather nicely captures that Reem used pen and white board only; a neat way of emphasising mastery of the material.
