Studying the singularity of LCM-type matrices via semilattice structures and their Möbius functions

Mika Mattila, Pentti Haukkanen, Jori Mäntysalo

The invertibility of LCM matrices and their Hadamard powers have been studied a lot over the years by many authors. Bourque and Ligh conjectured in 1992 that the LCM matrix $[S]=[[…
