Located where simultaneously?
And simultaneous according to who?
At 0 in which frame of reference?
What is "left"? Is it the same as A or green, or is it something else completely?
What is an "axis of simultaneity"?
Only if they are both stationary relative to one another.
(Not sure what you had to make things so complicated by using A and black, and B and green (and left and right?) to refer to the same things.)
What is 'f'?
Why isn't the length of his ship d in his frame of reference?
What is 'e' ?
What is 'g'?
You are saying that g2 = f /e ? (Or maybe g2 = f /e? I am confused by your constantly changing names for things)
How did you calculate this?
What does this mean? (It sounds wrong, but unless you explain it, it is hard to know.)
I'll ignore the rest, because without some explanation, I have no idea what you are trying to say. However, almost every statement appears to be incorrect.
