Explicit constructions of connections on the projective line with a maximally ramified irregular singularity

Neal Livesay, Daniel S. Sage, Bach Nguyen

The Deligne--Simpson problem is an existence problem for connections with specified local behavior. Almost all previous work on this problem has restricted attention to connections…

The Deligne-Simpson problem for connections on $G_{m}$ with a maximally ramified singularity

Maitreyee C. Kulkarni, Neal Livesay, Jacob P. Matherne +2

The classical additive Deligne-Simpson problem is the existence problem for Fuchsian connections with residues at the singular points in specified adjoint orbits. Crawley-Boevey fo…

The Absolute Orders on the Coxeter Groups $A_{n}$ and $B_{n}$ are Sperner

Lawrence H. Harper, Gene B. Kim, Neal Livesay

Over 50 years ago, Rota posted the following celebrated `Research Problem': prove or disprove that the partial order of partitions on an $n$ -set (i.e., the refinement order) is Spe…
