Query: Generic absence of strong singularities in loop quantum Bianchi-IX
  spacetimes   We study the generic resolution of strong singularities in loop quantized
effective Bianchi-IX spacetime in two different quantizations - the connection
operator based `A' quantization and the extrinsic curvature based `K'
quantization. We show that in the effective spacetime description with
arbitrary matter content, it is necessary to include inverse triad corrections
to resolve all the strong singularities in the `A' quantization. Whereas in the
`K' quantization these results can be obtained without including inverse triad
corrections. Under these conditions, the energy density, expansion and shear
scalars for both of the quantization prescriptions are bounded. Notably, both
the quantizations can result in potentially curvature divergent events if
matter content allows divergences in the partial derivatives of the energy
density with respect to the triad variables at a finite energy density. Such
events are found to be weak curvature singularities beyond which geodesics can
be extended in the effective spacetime. Our results show that all potential
strong curvature singularities of the classical theory are forbidden in
Bianchi-IX spacetime in loop quantum cosmology and geodesic evolution never
breaks down for such events.
