 >Identifying Riemannian singularities with regular non-Riemannian geometry
 </a>\nby Miok Park (IBS-CTPU) as part of Advances in Theoretical Physics 2
 022\n\n\nAbstract\nAdmitting non-Riemannian geometries\, Double Field Theo
 ry extends the notion of spacetime beyond the Riemannian paradigm. We iden
 tify a class of singular spacetimes known in General Relativity with regul
 ar non-Riemannian geometries. The former divergences merely correspond to 
 coordinate singularities of the generalised metric for the latter. Compute
 d in string frame\, they feature an impenetrable non-Riemannian sphere out
 side of which geodesics are complete with no singular deviation. Approachi
 ng the non-Riemannian points\, particles freeze and strings become (anti-)
 chiral.\n
