Asymptotic expansions of the Gauss hypergeometric function are derived for large absolute values of the complex parameters a,b,c (c and for fixed values of the complex variable z . Assuming , and that Re and Re are bounded below or two- sided bounded it is shown that the -plane can be divided in two sectors dependent on the value of z so that
in the sector including the positive real axis Pochhammer symbol) and F(a,b;c;z)
in the remaining sector. In particular, it follows that (i) is not valid for all z with , when the complex parameter c tends arbitrary to infinity. This refutes an assertion in the well-known book “Higher transcendental functions”, Vol. 1 by A. Erdélyi et. al. (1951; Zbl 0051.303).
