Lebesgue's density theorem: Difference between revisions

"For almost every point x of A the density exists and is equal to 1" is the correct statement of the theorem, "is equal to 0 or 1" is to weak. Apparently there was a contamination with the next line of the article that refers to x in R^n.

The '''Burning Ship [[fractal]]''', first described and created by Michael Michelitsch and [[Otto E. Rössler]] in 1992, is generated by iterating the function:
 
:<math>z_{n+1} = (|\operatorname{Re} \left(z_n\right)|+i|\operatorname{Im} \left(z_n\right)|)^2 + c, \quad z_0=0</math>
 
in the [[complex plane]] <math>\mathbb{C}</math> which will either escape or remain bounded. The difference between this calculation and that for the [[Mandelbrot set]] is that the real and imaginary components are set to their respective absolute values before squaring at each iteration. The mapping is non-analytic because its real and imaginary parts do not obey the [[Cauchy&ndash;Riemann equations]].<ref>Michael Michelitsch and Otto E. Rössler (1992).

Hi there, I am Alyson Pomerleau and I think it seems fairly good when you say it. My day occupation is an info officer but I've already applied for another 1. To climb is something she would by no means give up. Kentucky is exactly where I've always been residing.

Take a look at my web page: real psychic readings; you can try this out,
