- The recent discussion about whether P=NP made me wonder.....
-
- There are quite a number of theorems beginning, "if P =|= NP then..."; and
- presumably masses beginning "if P = NP then..." .
-
- In a different area, number theory, there are a great many theorems beginning
- "if Riemann's hypothesis is true then...", and presumably one or two beginning
- "if Riemann's hypothesis is false then...." .
-
- So what happens to these results of the "wrong" sort, when and if the
- conditioning result is decided. Do they suddenly become uninteresting ? Do
- they suddenly lose all their information content, or do they still retain
- some ?
-
- ( Perhaps they should be solemnly excised from all copies ofjournals, like
- the Stalinesque instructions to encyclopaedia owners when a politician
- suddenly fell from favor...... ).
-
- Well, it's a pretty vague question; but perhaps someone can think of a pretty
- vague but sensible answer ?
