    • Cesàro’s Formula in an Algebraic Setting 

      Haukkanen, Pentti (2025)
      article
      Let τ(n) denote the number of positive divisors of n. Cesàro’s formula says that the number of ordered pairs ≺a,b≻ of integers such that 1 ≤ a,b ≤ n and [a,b] = n is equal to τ(n2), where [a,b] is the least common multiple ...
