Slowly varying function if for all , . A function for which the limit is finite but nonzero for every , is called a "regularly varying function". These definitions are due to Jovan Karamata. Regularly varying functions have some important properties: a partial list of them is reported below. More extensive analyses of the properties characterizing regular variation are presented in the monograph by . . The limit in and is uniform if is restricted to a compact interval. . Every regularly varying function is of the form where Note. This implies that the function in has necessarily to be of the following
