  This paper deals with an attempt of proof of the Riemann Hypothesis (RH). Let
$T>10^{10}$ arbitrarily large. Let the region $\Omega_T=\Big\{z=x+i y\ \Big|\
\frac{1}{2}<x<1, \ 0<y<T\Big\}.$ There is a finite number $N_T$ of roots of
$\zeta(z)$ in $\Omega_T$. The aim of the paper is to prove that $N_T=0$.
Suppose that $N_T>0$. There exists at least one root $\rho=\frac{1}{2}+{\bf
u}+i\gamma $ whose real part is greater or equal to the real part of all the
other roots in $\Omega_T$. Let $v\geq \frac{3}{2}$. Let $\varepsilon>0$
arbitrarily small. We prove that $f(z)=\frac{\zeta'(z)}{\zeta(z)}$ is analytic
in the open disk $\Omega_\varepsilon=\Big\{
\Big|z-\Big(\rho+\frac{\varepsilon}{2}+v\Big)\Big|\Big\}< v.$ Let
$s=\rho+\varepsilon$. We prove, from the Taylor series of $\zeta(s)$, that
$f(s)\sim \frac{1}{\varepsilon}\rightarrow \infty$ when $\varepsilon\rightarrow
0$, and that, through the representation of $f(s)$ as a Taylor series,
$f(s)=f(c_0)-(v-\frac{\varepsilon}{2})f'(c_0)
+\frac{(v-\frac{\varepsilon}{2})^2}{2!}f''(c_0)-\frac{(v-\frac{\varepsilon}{2})^3}{3!}f^{(3)}(c_0)+\dots\mbox{\
for\ }c_0=\rho+\frac{\varepsilon}{2}+v,$ in $\Omega_\varepsilon$, that
$f(s)\not\rightarrow \infty$ when $\varepsilon\rightarrow 0$, a contradiction
which allows us to prove RH.
