Hi Georges,

if you start from OMs as basic, then a branch is a set of  OMs (only 
"consistent"/ordered set ?). Then it means a branch is unique. Some part of 
different branches could overlap, but as I don't understand what could be an 
absolute measure (meaning it never change and is fixed forever) between all 
branches, I don't see how to assert the measure of a branch... Also viewing 
from this point each 1st pov "lives" in its own branch (as a branch is an 
ordered set of OMs which in turn is associated to a 1st person).

  
Hi Quentin, Stathis, Bruno

It all depends how you see the plenitude, OMs and the branching. Is consciousness like a traveller in a network of roads traversing the plenitude, some roads branching some roads merging?

If yes then you could have several independent consciousness occupying the same spot, or the same OM. Then their measure at that spot is their sum. This approach is a third person point of view and it leads to the concept of absolute measure.

If you see consiousness as the road itself, then measure is not increased after a merge and does not decrease after a split. An OM is just a point on the road. If the road turns unexpectedly to avoids an obstacle (like quantum suicide or just plain death), then consiousness will just move on into a direction which has a low 3-rd person probability but unity first person probability. Viewing consciousness as a network of roads is a first person point of view and it leads to the concept of relative measure: Measure is always 1 where you are. >From a given point you may reach many points - Then measure increases with respect to that point. Or reversibly, from many points you may reach only one point. Then measure decreases.

The crux of the matter is the concept of indistinguishability: whether you consider two identical persons (OMs) occupying two identical universes the same person (point on the road). It is clear that if you consider the problem from the information angle, then duplication of information does not increase the measure of that information. This would support the relative interpretation of measure.

I still think that if you double everything and then annihilate only the
doubled person, the probability will be 1.
        
Actually I agree with this.
      
So far we have been talking about splitting universes and people. Let's
consider the case where two branches of the universe merge. In other
words, two different paths eventually happen to become identical - Of
course when this happens all their branching futures also become
identical. Would you say that such a double branch has double the
measure of a single branch even though the two branches are totally
indistinguishable? How can you possibly assert that any branch is
single, double, or a bundle composed of any number of identical
individual branches?
