In this paper we show that at least 2/5 of the zeros of the Riemann zeta-function are simple and on the critical line. Our method is a refinement of the method Levinson  used when he showed that at least 1/3 of the zeros are on the critical line (and are simple, äs observed by Heath-Brown  and, independently, by Seiberg). The main new element here is the use of a mollifier of length y=T with = 4/7 — whereas in Levinson's theorem the mollifier has 0 = 1/2 — . The work  of Deshouillers… Expand

At least two fifths of the zeros of the Riemann zeta function are on the critical line
Of central importance in number theory is the distribution of the complex zeros of f(s), all of which are in the critical strip 0 < a < 1 and are symmetrically located about the real axis and aboutExpand
Zeros of Lattice Sums: 3. Reduction of the Generalised Riemann Hypothesis to Specific Geometries
The location of zeros of the basic double sum over the square lattice is studied. This sum can be represented in terms of the product of the Riemann zeta function and the Dirichlet beta function, soExpand
Long mollifiers of the Riemann Zeta-function
The best current bounds for the proportion of zeros of ζ( s ) on the critical line are due to Conrey [C], using Levinson's method [Lev]. This method can also be used to detect simple zeros on theExpand
Distribution of the zeros of the Riemann Zeta function
One of the most celebrated problem 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. Even if this famousExpand
Zeros of the Riemann Zeta-function on the critical line
It was shown by Selberg  that the Riemann Zeta-function has at least cT log T zeros on the critical line up to height T, for some positive absolute constant c. Indeed Selberg’s method counts onlyExpand

Abstract. Denote by tn the distinct positive ordinates of zeros of the Riemann zeta-function ζ(s) on the critical line in ascending order. We prove ∑ tn6T |ζ ′( 1 2 + itn)| ¿ T (log T ), and ∑ tn6TExpand

Results of a multipart work are outlined. Use is made therein of the conjunction of the Riemann hypothesis, RH, and hypotheses advanced by the author. Let z(n) be the nth nonreal zero of the RiemannExpand
A Study of L-Functions: At The Edge of the Critical Strip and Within
In analytic number theory, and increasingly in other surprising places, L-functions arise naturally when describing algebraic and geometric phenomena. For example, when attempting to prove the PrimeExpand
