I've written my first little #Scittle app today, and I'm impressed. To be able to write in-browser code in #Clojure is so much nicer than #Javascript. I have some issues to fix and some enhancement…

Calogero-Sutherland hyperbolic system and Heckman-Opdam $\mathfrak{gl}_n$ hypergeometric function
We prove equivalence of two integral representations for the wave functions of hyperbolic Calogero-Sutherland system. For this we study two families of Baxter operators related to hyperbolic Calogero-Sutherland and rational Ruijsenaars models; the first one as a limit from hyperbolic Ruijsenaars system, while the second one independently. Besides, computing asymptotics of integral representations and also the value at zero point, we identify them with renormalized Heckman-Opdam $\mathfrak{gl}_n…

@… Would love to see this integrate with GitHub more, particularly the classroom functionality.
I’ve spent a good few hours on and off over the years helping one of our local CompSci teachers with all of the work around “How do I go from an exercise I want students to complete, to an actual assignment in GH Classroom, a template repo, and a GH Action pip…

The Hands-Up Problem and How to Deal With It: Secondary School Teachers' Experiences of Debugging in the Classroom
Debugging is a vital but challenging skill for beginner programmers to learn. It is also a difficult skill to teach. For secondary school teachers, who may lack time or relevant knowledge, honing students' understanding of debugging can be a daunting task. Despite this, little research has explored their perspectives of debugging. To this end, we investigated secondary teachers' experiences of debugging in the classroom, with a focus on text-based programming. Through thematic analysis of nine …

Intersections of Schubert varieties and smooth $T$-stable subvarieties of flag varieties
A smooth projective variety with an action of a torus admits a cell decomposition, called the Bialynicki-Birula decomposition. Singularities of the closures of these cells are not well-known. One of the examples of such closures is a Schubert variety in a flag variety G/B, and there are several criteria for the smoothness of Schubert varieties. In this paper, we focus on the closures of Bialynicki-Birula cells in regular semisimple Hessenberg varieties Hess(s,h), called Hessenberg Schubert vari…
