Abstract

Let P be a finite set of finite rational primes. In this article, we prove the existence of infinitely many positive integers \(n_i\) such that corresponding to each such integer \(n_i\), there are infinitely many number fields L (both totally real and totally imaginary) of degree \(n_i\) which ramify exactly at \(|P|+1\) finite rational primes and admitting an infinite p-class field tower, for all \(p \in P\), simultaneously.
