We have:

This is nonsense, and demonstrates that you
don't know what an event is.
e2 is the event that clock A and clock B' are adjacent
tA'(e2) is meaningless.
It is obvious that tA'(e2) has a meaning for A'.e2 is short for "the event that clock A and clock B' are adjacent"
It is the time at which in his frame of reference (A'), the event E2 exists.
Paul, Paul, you can't say it's meaningless. A little more consideration for the other posters, and please a little more practical intelligence: there is indeed a moment, where, for A, the event e2 exists in his frame of reference, and if A' was synchronized at the start, there will be a time, and only one time of e2 that will be written on his watch.
We can easily, if we correctly master the notion of relativistic simultaneity and the notions of relative chronotropies,
reveal what this time written on the clock A' thus synchronized during e1 will be: tA'(e1)=0.
I beg you not to say that it is absurd or meaningless.At event e1 tA = 0, at event e2 tA = (d/v)⋅√(1−v²/c²) = 0.75 s
How to proceed?
We KNOW that the travel time of A in A'B'
will be equal to the distance A'B' in R' divided by the apparent escape velocity of an object moving at v=0.8c.And what will you escape from?
This is unavoidable and it is mathematical.Nonsense.
Let tA'(e2)=tA'(e1)+(A'B'/Vapp')
Let tA'(e2)= 0 + 3.10^8/(4/9)c
tA'(2)=2.25 sec
Please note, I am talking about the exact time when A' actually perceives e2 in direct-live, and which represents the real time of things.Please note, I am talking about the exact time when Paul
If we want to judge, and count based on synchronization abstract, based on "the transverse speed of light", it is necessary remove a second of anisochrony between A' and B'. Which gives a time supposed (but false) of 1.25 sec.Well said!
Please confirm that you have understood and that you validate, which will allow us to go further and explain all the predictive values that I have already given, but without explaining yet.I have understood that we have to remove a second based on
