Sophomore's dream function: asymptotics, complex plane behavior and relation to the error function

V. Yu. Irkhin

Sophomore's dream sum $S = \sum_{n = 1}^{\infty} n^{- n}$ is extended to the function $f (t, a) = t \int_{0}^{1} (a x)^{- t x} d x$ with $f (1, 1) = S$ . Asymptotic behavior for a large $∣ t ∣$ is obtained…
