  • Liouville¿Green transformations of the Gauss hypergeometric equation with changes of variable are considered. When p+q=1, p=0 or q=0 these transformations, together with the application of Sturm theorems, lead to properties satisfied by all the real zeros xi of any of its solutions in the interval (0,1). Global bounds on the differences z(xk+1)-z(xk), 0
