Sudden singularities in semiclassical gravity
It has been claimed in a recent paper \cite{bbfhd12} that sudden
singularities will survive in semiclassical gravity. This issue is here
carefully reviewed, pointing out that such conclusion, even if valid under some
specific conditions, does not stand in other cases. An explicit example is
studied in detail to support our statement, stemming from these other
situations, that quantum effects may in fact drastically modify the behavior of
sudden singularities.Comment: Accepted for publication in PR
