Abstract
Scaling functions that generate a multiresolution analysis (MRA) satisfy, among other conditions, the so-called <<two-scale relation>> (TSR). In this paper we discuss a number of properties that follow from the TSR alone, independently of any MRA: position of zeros (mainly for continuous scaling functions), existence theorems (using fixed point and eigenvalue arguments) and orthogonality relation between integer translates.
