Global solutions for semilinear rough partial differential equations
Robert Hesse, Alexandra Neamtu
We construct global-in-time solutions for semilinear parabolic rough partial differential equations. We work on a scale of Banach spaces tailored to the controlled rough path appro…

Global solutions and random dynamical systems for rough evolution equations
Robert Hesse, Alexandra Neamtu
We consider infinite-dimensional parabolic rough evolution equations. Using regularizing properties of analytic semigroups we prove global-in-time existence of solutions and invest…

Local mild solutions for rough stochastic partial differential equations
Robert Hesse, Alexandra Neamtu
We investigate mild solutions for stochastic evolution equations driven by a fractional Brownian motion (fBm) with Hurst parameter H in (1/3, 1/2] in infinite-dimensional Banach sp…
