In number theory, g(n) is a function that is often used to express certain properties of integers or to manipulate summation processes, particularly in the context of Abel's summation formula. This function can represent a variety of different sequences or functions depending on the specific problem or application, often relating to sums of arithmetic functions or Dirichlet series. g(n) helps bridge the gap between discrete sums and continuous functions, facilitating analysis in analytic number theory.
congrats on reading the definition of g(n). now let's actually learn it.
