We use the result to show lower bounds on the I/O-complexity on a number of problems where known techniques only give trivial bounds. Among these ar

Our algorithms maintain a separator in expected time .(log .) and maintain a separator tree in expected time .(log..)

This paper provides the first partial solution to the problem. It gives a new combinatorial characterization of orthogonal drawings based on the concept of
