We derive 'normal forms' for the defining equations of recursive towers of function fields over finite fields.Specially interesting are the cases of towers of Kummer type and towers of Artin-Schreier type.We introduce a notion of an f-tower, where f(T) is a rational function on the projective line over the finite field,and we show that several known 'good' towers are indeed f-towers for some f(T).
