The newly hatched internet economy took off, the Cold War was consigned to history, two separate teams were racing to sequence the human genome, and once that was in the databanks, surely we would understand much more about our diseases and develop new cures based on the genetic insights. And Al Gore might become US president and do someth...

The linear discrepancy of a poset P is the least k such that there is a linear extension L of P such that if x and y are incomparable, then |hL(x)− hL(y)| ≤ k. Whereas the weak discrepancy is the least k such that there is a weak extension W of P such that if x and y are incomparable, then |hW (x)− hW (y)| ≤ k. This paper resolves a question of Tanenbaum, Trenk, and Fishburn on characterizing w...
