We study transcendental values of the logarithm of the gamma function. For instance, we show that for any rational number x with 0 < x < 1, the number log Γ (x) + log Γ (1 - x) is transcendental with at most one possible exception. Assuming Schanuel's conjecture, this possible exception can be ruled out. Further, we derive a variety of results on the Γ-function as well as the transcendence of certain series of the form ∑n = 1∞ P (n) / Q (n), where P (x) and Q (x) are polynomials with algebraic coefficients. © 2009 Elsevier Inc.
