Crossness Pumping Station: seduced by symmetry — Anthony Baines Photography
Last week, I was lucky enough to visit the Crossness Pumping Station in South-East London . It is variously known as the "Cathedral in the Marshes" or, more bluntly, the "Cathedral of Sewage". It is a former Victorian sewage pumping station, opened in 1865; it continued to ope

Bounds on Functionality and Symmetric Difference -- Two Intriguing Graph Parameters
Functionality ($\mathrm{fun}$) is a graph parameter that generalizes graph degeneracy defined by Alecu et al. [JCTB, 2021]. They research the relation of functionality to many other graphs parameters (tree-width, clique-width, VC-dimension, etc.). Extending their research, we completely characterize the functionality of random graph $G(n,p)$ for all possible $p$. We provide matching (up to a constant factor) lower and upper bound for a large range of $p$. It follows from our bounds for $G(n,p)$…
