On the $a$-points of the derivatives of the Riemann zeta function

Abstract

We prove three results on the $a$-points of the derivatives of the Riemann zeta function. The first result is a formula of the Riemann-von Mangoldt type; we estimate the number of the $a$-points of the derivatives of the Riemann zeta function. The second result is on certain exponential sum involving $a$-points. The third result is an analogue of the zero density theorem. We count the $a$-points of the derivatives of the Riemann zeta function in $1/2-(\log \log T{)}^2/\log T<\Re s<1/2+(\log \log T{)}^2/\log T$.
