Generic Hausdorff dimension conjecture for Takagi-function abscissa level sets

About 16 years old · traced to

Let τ\tau be the Takagi function, and for x∈[0,1]x\in[0,1] let L(τ(x))L(\tau(x)) denote the level set of points having Takagi value τ(x)\tau(x). A set of abscissa points has full Lebesgue measure if its complement in [0,1][0,1] has Lebesgue measure zero.

Abscissa generic level sets. A full Lebesgue measure set of abscissa points x∈[0,1]x\in[0,1] have level sets L(τ(x))L(\tau(x)) that are uncountable and have Hausdorff dimension 00.

This conjecture refines the known almost-everywhere result that generic local level sets are uncountable and have Hausdorff dimension zero, by asserting the same properties for the full level sets L(τ(x))L(\tau(x)).
