Explicit upper bound for the average number of divisors of irreducible quadratic polynomials
Consider the divisor sum [Formula: see text] for integers b and c. We extract an asymptotic formula for the average divisor sum in a convenient form, and provide an explicit upper bound for this sum with the correct main term. As an application we give an improvement of the maximal possible number o...
