The Wikipedia entry for Egan's 2002 novel Schild's Ladder describes it as "...perhaps the hardest science fiction ever published by Egan, filled with non-trivial mathematics and theoretical physics." - but folks have not, it seems, been intimidated by such a technical appraisal, as is apparent from this reissue from Gollancz, which I reckon is the fourth or fifth separate edition they have put out since they first published in the UK five years ago.
