Hey guys, I need your help. I am not sure if this is the right part of the forum to ask this question. So I started reading papers about the Lyapunov Exponent, but there is something I do not understand in the formula. Why ? It seems logical that we want because we want to get the Exponent at a certain point and therefore the startingpoints should be really close together. I added a text from a book which says, that we have , because then my will fluctuate around a finite value, but I have no clue why an exponential function should do this. Maybe somebody can help me.
