Well-posedness by noise for linear advection of \(k\)-forms

In this work, we extend existing well-posedness by noise results for the stochastic transport and continuity equations by treating them as special cases of the linear advection equation of \(k\)-forms, which arises naturally in geometric fluid dynamics. In particular, we prove the existence and uniq...

description In this work, we extend existing well-posedness by noise results for the stochastic transport and continuity equations by treating them as special cases of the linear advection equation of \(k\)-forms, which arises naturally in geometric fluid dynamics. In particular, we prove the existence and uniqueness of weak \(L^p\)-solutions to the stochastic linear advection equation of \(k\)-forms that is driven by a H\"older continuous, \(W^{1,1}_{loc}\) drift and smooth diffusion vector fields, such that the equation without noise admits infinitely many solutions.
