From the #PurdueFortWayne 🐘 YouTube site, a short video from this year's Commencement ceremony, about "What our faculty is wearing at commencement".

New arXiv preprint!  With my #PurdueFortWayne colleague Yifei Pan.  🐘 Here's a thread (1/n)

Constructing Discontinuous but Locally Bounded Rational Functions using Łojasiewicz Inequalities
For real multivariate polynomials $P$ and $Q$ both vanishing at a point, if the zero set of $Q$ is contained in the zero set of $P$, then there exists a rational function of the form $P^{p}/Q^{q}$ which is locally bounded and such that its extension that vanishes on the zero set of $Q$ is discontinuous. The proof uses inequalities of Lojasiewicz.

My photos from today's end-of-semester social event for the #PurdueFortWayne College of Science. 🐘 I had to leave in time for class so I didn't try the kayaking on the St. Joseph River myself. 🛶
