Title：On properties of Takagi-like functions

Abstract：Takagi function is a well-known continuous but nowhere differentiable function defined over the real numbers. In this talk, we introduce Takagi-like functions, a slight generalization of Takagi functions. We show that Takagi-like functions preserve rationality, namely, they send rational numbers to rational numbers. This is joint work with Yangyang Chen and Hongyuan Yu.
