"Singularities" in spacetimes with diverging higher-order curvature invariants
D. A. Konkowski, T. M. Helliwell
After reviewing the definitions of classical and quantum singularities, it is shown by example that if zeroth-order curvature invariants are regular, a diverging higher-order curva…

Quantum particle behavior in classically singular spacetimes
D. A. Konkowski, T. M. Helliwell
We review the classical and quantum singularity structure of a broad class of spacetimes with asymptotically power-law behavior near the origin. Quantum considerations "heal" a lar…

Classical and quantum properties of a 2-sphere singularity
T. M. Helliwell, D. A. Konkowski
Recently Boehmer and Lobo have shown that a metric due to Florides, which has been used as an interior Schwarzschild solution, can be extended to reveal a classical singularity tha…
