As far as I know non-parametric in non-parametric Bayesian modelling means infinite number of parameters. Therefore I expected the same meaning in non-parametric empirical Bayes methods, however I am a little bit confused, because I cannot find infinite number of parameters in the description of...
Usually positive Ljapunov exponent is said to be a condition for chaos,
and the strange atractor is so.
Are there any theorem which shows that the two condition is equivalent?
They are necessary and sufficent conditions?
I don't understand how it is possible that you don't understand me :)
It is very hard to imagine (if you are a physicist)
that there exist a higher dimensional physical World,
but our world is only a surface in that World.
We can never prove its physical existence.
That higher dimension...
I am talking about brane worlds, and not branes in string theory. Branes in string theory is totally different. Brane in brane-world theories represent the whole Universe and not a particle.
Yes, most of the brane-world theories the Universe is a 3+1 dimensional infinitesimal surface in a...
I say that:
Most of the models assume a lower dimensional surface (=infinitely thin),
and not a same dimensional but thin physical surface.
If you know something belongs to the latter one
please link it for me.
In most of the brane world models:
our world is supposed to be an infinite thick mathematical surface
in the higher dimensional world.
Which is very curious.
Are there any model in which the thickness of the "surface" is finite?
Please, could anyone submit a good paper to me in this topic?
I need a free description with illustrations on 4D knots theory,
especially the 4D generalization of Reidermeister moves and
the movie represantation.
Where can I find a freely available paper?
