Taylor estimate for differential equations driven by $Π$ -rough paths

Danyu Yang

We obtain a remainder estimate for the truncated Taylor expansion for differential equations driven by weakly geometric $Π$ -rough paths for $Π = (p_{1}, \dots, p_{k})$ ,…

Notes on area operator, geometric 2-rough paths and Young integral when p^-1+q^-1=1

Danyu Yang

1.When equipped with 2-rough norm and restricted to continuous paths with bounded variation, the area operator is a closable unbounded operator. 2.The area defined through Riemann-…
