The Takagi Function and Its Properties
Jeffrey C. Lagarias · arXiv (Cornell University) · 2011
The Takagi function is a continuous non-differentiable function on [0,1] introduced by Teiji Takagi in 1903. It has since appeared in a surprising number of different mathematical contexts, including mathematical analysis, probability theory and number theory. This paper surveys the known properties of this function as it relates to these fields.
