Abstract
In this paper (part II), we analyze various equations concerning the Isoperimetric
Theorems. We describe the new possible mathematical connections with some sectors
of Number Theory, String Theory and Inflationary Cosmology

Introduction
In 1983, it was shown that inflation could be eternal, leading to a multiverse in which
space is broken up into bubbles or patches whose properties differ from patch to
patch spanning all physical possibilities.
When the false vacuum decays, the lower-energy true vacuum forms through a
process known as bubble nucleation. In this process, instanton effects cause a
bubble containing the true vacuum to appear. The walls of the bubble (or domain
walls) have a positive surface tension, as energy is expended as the fields roll over
the potential barrier to the true vacuum.
In mathematics, a ball is the space bounded by a sphere. It may be a closed ball
(including the boundary points that constitute the sphere) or an open ball (excluding
them). (From Wikipedia)
We propose that some equations concerning the balls, thus various sectors and
theorems of Geometric Measure Theory, can be related with several parameters of
some cosmological models as the “Multiverse” and the “Eternal Inflation” linked to
it, which provides that space is divided into bubbles or patches whose properties
differ from patch to patch and spanning all physical possibilities.

QUANTITATIVE ISOPERIMETRIC INEQUALITIES - Inserted: 12 nov 2007 - Last

We have:
An isoperimetric inequality relates the perimeter to the area of a closed curve in the
plane. If P is the perimeter of the curve and A is the area of the region enclosed by
the curve, the inequality has the form
4πA P
2
In the case of a circle of radius r we have A = πr
2
and P = 2πr, and replacing these
in the inequality we see that the circle, among all the curves of fixed perimeter,
maximizes the area. In fact, the circle is the only curve that maximizes the area.

196884/196883 is a fundamental number of the following j-invariant
(In mathematics, Felix Klein's j-invariant or j function, regarded as a function of
a complex variable τ, is a modular function of weight zero for SL(2, Z) defined on
the upper half plane of complex numbers. Several remarkable properties of j have to
do with its q expansion (Fourier series expansion), written as a Laurent series in
terms of q = e
2πiτ

Note that j has a simple pole at the cusp, so its q-expansion has no terms below q

All the Fourier coefficients are integers, which results in several almost integers,
notably Ramanujan's constant:
The asymptotic formula for the coefficient of q

is given by
as can be proved by the HardyLittlewood circle method)

Observations
We note that, from the number 8, we obtain as follows:
We notice how from the numbers 8 and 2 we get 64, 1024, 4096 and 8192, and that 8
is the fundamental number. In fact 8
2
= 64, 8
3
= 512, 8
4
= 4096. We define it
"fundamental number", since 8 is a Fibonacci number, which by rule, divided by the
previous one, which is 5, gives 1.6 , a value that tends to the golden ratio, as for all
numbers in the Fibonacci sequence
116
“Golden” Range
Finally we note how 8
2
= 64, multiplied by 27, to which we add 1, is equal to 1729,
the so-called "Hardy-Ramanujan number". Then taking the 15th root of 1729, we
obtain a value close to ζ(2) that 1.6438 ..., which, in turn, is included in the range of
what we call "golden numbers"
Furthermore for all the results very near to 1728 or 1729, adding 64 = 8
2
, one obtain
values about equal to 1792 or 1793. These are values almost equal to the Planck
multipole spectrum frequency 1792.35 and to the hypothetical Gluino mass

In the above figure, it is said that: why a given shape of the extra dimensions?
Crucial, it determines the predictions for α”.
We propose that whatever shape the compactified dimensions are, their geometry
must be based on the values of the golden ratio and ζ(2), (the latter connected to 1728
or 1729, whose fifteenth root provides an excellent approximation to the above
mentioned value) which are recurrent as solutions of the equations that we are going
to develop. It is important to specify that the initial conditions are always values
belonging to a fundamental chapter of the work of S. Ramanujan "Modular equations
and Appoximations to Pi" (see references). These values are some multiples of 8 (64
and 4096), 276, which added to 4096, is equal to 4372, and finally e

7.021621519*10^-15 ; 1.57986484181*10^-14 ; 7.021621519159*10^-17 ;
-4.38851344947*10^-16
we obtain, after some calculations:
sqrt[1/(2Pi)(7.021621519*10^-15 + 1.57986484181*10^-14 +7.021621519*10^-17 -

Input interpretation:
Result:

We note that:
1/55*(([(((1/[(7.021621519*10^-15 + 1.57986484181*10^-14 +7.021621519*10^-17

Input interpretation:
Result:
1.6181818182… result that is a very good approximation to the value of the golden
ratio 1.618033988749...
