A probabilistic approach to the -variation of classical fractal functions with critical roughness
Xiyue Han, Alexander Schied, Zhenyuan Zhang
We consider Weierstraß and Takagi-van der Waerden functions with critical degree of roughness. In this case, the functions have vanishing variation for all bu…

Step roots of Littlewood polynomials and the extrema of functions in the Takagi class
Xiyue Han, Alexander Schied
We give a new approach to characterizing and computing the set of global maximizers and minimizers of the functions in the Takagi class and, in particular, of the Takagi--Landsberg…
