Distribution and finding intervals contained of the zeros
of the Riemann Zeta function.
(2)
Abstract.. One of the most celebrated problems of mathematics is the Riemann hypothesis which states that all the non trivial zeros of the Zeta-function lie on the critical line s = 1/2.
all the non trivial zeros lie in the critical strip, the number of such zeros with ordinate less than T is proportional to T log T, most zeros concentrate along the critical line s = 1/2, there exists an infinity of zeros on the critical line and moreover, more than two fifth of the zeros are on the critical line.Finding the roots by Lagrange method demarcating the intervals whose are not trivial zeros of the Zeta-function.
INTRODUCTION
1.1Forms of the Riemann ζfunction..
The Riemann ζ function has two types of zeros: even negative integers see the func- tional equation set..
usually refered to as the trivial zeros, and non-trivial complex zeros.
It is proved that any non-trivial zero lies in the open strip

#1.1 From Riemann Siegel Formula
An important part of evaluation of ζ is along the critical line. The Riemann Siegel method involves estimates of the Rieman Siegel Z-function, which is denned as
where _ is the Riemann-Siegel _ function:
Both Z(t) and θ(t) can be estimated relatively fast, which yields an efficient algorithm to calculate on the critical line. Riemann-Siegel ζ function has an asymptotic expansion
which is not convergent, but the terms decrease very rapidly for t at all large.
where Φj are entire functions which may be expressed in terms of derivatives of
The error term Rn( ) is bounded above by O
(
(2n3)/4)
. Typically, mathematicianshave chosen n = 2, and use some conservative bound for their calculation. For example, Brent used |R2( )| < 3
(

for > 2000.#1.2 Asymptotic equation satisfied by the n-th zero.
Let us start with the completed Riemann zeta function defined by
where s = 1/2 + it. In quantum statistical physics, this function is the free energy of a gas of mass less bosonic particles in d spatial dimensions when s = d + 1 up to the overall power of the temperature
1
d
T
.Under a \modular" transformation that exchanges one spatial coordinate with Euclidean time, if one analytically continues d, physical arguments shows that it must have the symmetry..
This is the fundamental, and amazing, functional equation satisfied by the _ζ-function, which was proven by Riemann using only complex analysis. For several different ways of proving (2) see [10].
(4)
Now consider Stirling's approximation
which is valid for large t. Under this condition we also have
Therefore, using the polar representation
and the above expansions, we can write
Where
The above approximation is very accurate. For t as low as 100, it evaluates
correctly to one part in 106. Above, we are assuming t > 0. The results for t < 0 follows trivially from the relation
(1)
Now let ρ = + it be a Riemann zero. Then Αrgζ(ρ) can be defined by the limit (2)
For reasons that are explained below, it is important that 0 < δ<= 1. This limit in general is not zero. For instance, for the first Riemann zero given by
ρ=1/2 + i 14:1347, we have arg ζ (ρ) = 0.157873919880941213041945. On the critical line s = 1/2 + it, if t does not correspond to the imaginary part of a zero, the well-known function
Is defined by continuous variation along the straight lines starting from 2, then up to 2+it and finally to 1/2 + it, where argζ(2) = 0. From (1) we have
which implies that
And θ( ,-t) = -θ( , t). Denoting
we then have
From (2) we also have
therefore
(5)
Let us now approach a zero ρ =1/2+it through the δ 0+ limit. From (1) it follows that ζ(s) and χ(s) have the same zeros on the critical strip, so it is enough to consider the zeros of χ(s). From (2) we see that if ρ is a zero so is 1-ρ. Then we clearly have
where we have de_ned
The second equality in (8) follows from A = A0. Then, in the limit _ δ 0+, a zero corresponds to A = 0, B = 0 or both. They can simultaneously be zero since they are not independent.If B = 0 then A = 0, since A |ζ|. However, the converse is not necessarily true. In order to be more rigorous, one should consider the limits _ ! 0+ separately in A verses B; below we will consider taking the limit in B Firrst
The non-trivial behavior of A is mostly dictated by |ζ|. On the other hand there is much more structure in B since it contains the phases of χ(s) and χ(1 - s). It describes oscillations on the complex plane and involves t log t and _ itself. Thus let us consider B = 0. We will provide sample evidence that all zeros are characterized by this equation. The general solution of B = 0 is given by
which are a family of curves t( ). However, since χ(s) is analytic on the critical strip, we know that the zeros must be isolated points rather than curves, thus this general solution must be restricted. Let us choose the particular solution
(11)
On the critical line = ½ Пrom (7) аe СКve tСКt tСe _rst equation in (11) is already
satisfied. Then from the second equation in (11) we obtain
for n = 0,(+/-)1,(+/-)2,..., hence
Establishing the convention that zeros are labeled by positive integers,
where n = 1, 2,.... , we must replace n n – 2. Therefore, the imaginary parts of these zeros satisfy the transcendental equation
#1.3 Explicit formula
We now show that it is possible to obtain an approximate solution to the previous transcendental equations with an explicit formula. In this approximation, there is indeed a unique solution to the equation for every n. Let us introduce the Lambert W-function,
(6)
The multi-valued W-function cannot be expressed in terms of other known elementary functions.If we restrict attention to real-valued W(x) there are two branches. Since we are interested only in positive real-valued solutions, we just need
the principal branch where W is single-valued.
Let us start with the zeros of the W-function, described by equation (13). Consider its leading order approximation, or equivalently its average since
Then we have the transcendental equation
Through the transformation
this equation can be written a
Comparing with (61) we thus we obtain
where n = 1,2,...
Using the asymptotic behavior W(x) ~ log x for large x, the n-th zero is approximately given by
as already known. The distance between consecutive ordinates is then approximately equal to which tends to zero when n
#2. Categories of complex roots and intervals contained of the Riemann zeta function .
From page 9,10 in my the first part of the proof of the Riemann , applicable according to the method of solving equations of Lagrange,
Theorem of [Lagrange Expansion].Let f(z) and g(z) be functions of z analytic on and inside a Мontour C surrounНinР г = К, КnН let e sКtisПв tСe inequКlitв еpР(г)е < ег − Ке Пor Кll г
on the perimeter of C. Then the equation in has precisely one root u = u(a) in the interior of C..[7]. Let f(z) be analytic on and insideC. Then
So, according the theorem of Lagrange we have 3 categories complex roots of the Riemann zeta functions (Eq.set)

Bisection is the division of a given curve, figure, or interval into two equal parts (halves).A simple bisection procedure for iteratively converging on a solution which is known to lie inside some interval

proceeds by evaluating the function in question at the midpoint of the original interval2 b a

4.Epilogue
In accordance with the foregoing we can calculate the imaginary part of the Zeta function of various methods, which are approximate approach with as much want. The method Bisection suggests that the best because it is based on interval defined, which fully defines the multitude of roots but also the position of prime numbers.
