We proved the existence and uniqueness of global-in-time solutions in the W−1,p 1,p D-WD setting for abstract quasilinear parabolic PDEs with nonsmooth data and mixed boundary conditions, including a nonlinear source term with at most linear growth. Subsequently, we used a bootstrapping argument to achieve improved regularity, in particular Hölder continuity, of these global-in-time solutions within the functional-analytic setting of the interpolation scale of Bessel-potential dual spaces Hθ−1,p D = [W−1,p D, Lp ]θ with θ ∈ [0, 1] for the abstract equation under suitable additional assumptions. This was done by means of new nonautonomous maximal parabolic regularity results for nonautonomous differential operators with Hölder-continuous coefficients on Bessel-potential spaces. The upper limit for θ was derived from the maximum degree of Hölder continuity for solutions to an elliptic mixed boundary value problem in Lp.
