Assume that for a particular problem it can be proved that the matrices
are getting arbitrarily (even though very slowly) sparse with matrix
size.
Is it justified to claim that a sparse cholesky factorization of such a
matrix can be performed in at most O(NlogN)?
If no why not?
If yes with what specific algorithm?
Can you give a pointer to a particular paper?

Best regards,
Thomas
