摘要

We extend the semigroup approach used in Hoshino (https://arxiv.org/abs/2310.07396, 2019); Otto and Weber (Arch Ration Mech Anal 232:873–950, 2019) to provide alternative proofs of the reconstruction theorem and the multilevel Schauder estimate for singular modelled distributions. As an application of them, we construct the local-in-time solution of the two dimensional parabolic Anderson model with a non-translation invariant differential operator.
