In particular, if the diffusion is absent, then all smooth solutions with finite second moment can exist only locally in time. Nevertheless, one can ask whether global existence can be restored by adding a suitable noise to the equation, so that the dynamics are now stochastic. Inspired by the work of Buckmaster et al. (Int Math Res Not IMRN 23:9370–9385, 2020) showing that, with high probability, the inviscid SQG equation with random diffusion has global classical solutions, we investigate whether suitable random diffusion can restore global existence for a large class of active scalar equations in arbitrary dimension with possibly singular velocity fields. 2023-04-04T01:53:05Z 2023-04-04T01:53:05Z 2022 Book https://link.springer.com/article/10.1007/s00440-022-01171-8 https://dlib.phenikaa-uni.edu.vn/handle/PNK/7462 en application/pdf Springer
