,Der primäre Leberkrebs beim Tier,nables one to show lower bounds on the number of I/O-operations needed to solve a problem whenever a lower bound on the number of comparisons is known. 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

,Der primäre Leberkrebs beim Tier,here separators of size .=O(n.) for a set of points in R...We present randomized, dynamic algorithms to maintain separators and answer queries about a dynamically changing point set. 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
