Almost Primes of Almost Prime Index
Summary: A positive integer is called a \(k\)-\textit{almost prime} if it is a product of \(k\) prime numbers, counted with repetition. In this paper we consider \(j\)-almost primes of \(k\)-almost prime index for given integers \(j, k \geq 0\). We establish asymptotic estimates for the counting functions, \(n\)th occurrences, and reciprocal sums of ...Kinlaw, Paul +2 more
