Quadratic and $p$ -th variation of random signed Takagi--Landsberg bridges

Purba Das, Alexander Schied

We study random signed Takagi--Landsberg bridges with independent Rademacher Faber--Schauder coefficients. At index $H = 1/2$ , we prove that every fixed deterministic refining sequen…

Banach spaces of continuous paths with finite $p$ -th variation

Purba Das, Donghan Kim, Fang Rui Lim

We study pathwise $p$ -th variation of continuous paths on a compact interval along a fixed partition sequence. Although the class of continuous paths with finite $p$ -th variation i…
