“…[19,23,52,53,54,55,71,73], as well as in the context of the Reidemeister-Franz torsion [97,98]. In particular, in one dimension rather general and elegant results may be obtained, which has attracted the interest of mathematicians especially in the last decade or so [21,22,51,60,61,82,83,84]. In higher dimensions known results are restricted to highly symmetric configurations [13,14,16,23,44,45,46,50] or conformally related ones [10,11,16,47,48].…”
