Axiomatic theory of Sobolev spaces
Let \((X,d,\mu)\) be a set \(X\), equipped with a metric \(d\) and a Borel measure \(\mu\). For any \(u\in L^{\text{loc}}_p (X)\), so-called pseudo-gradients \(D[u]\) are introduced axiomatically, and on this basis \(p\)-Dirichlet energies, which, in turn, are used to introduce Sobolev spaces \(W^1_p (X)\).

Traces of multipliers in pairs of weighted Sobolev spaces
We prove that the pointwise multipliers acting in a pair of fractional Sobolev spaces form the space of boundary traces of multipliers in a pair of weighted Sobolev space of functions in a domain.

New characterizations of magnetic Sobolev spaces
We establish two new characterizations of magnetic Sobolev spaces for Lipschitz magnetic fields in terms of nonlocal functionals. The first one is related to the BBM formula, due to Bourgain, Brezis and Mironescu. The second one is related to the work of

Weighted Sobolev Spaces on Metric Measure Spaces
We investigate weighted Sobolev spaces on metric measure spaces $(X,d,m)$. Denoting by $\rho$ the weight function, we compare the space $W^{1,p}(X,d,\rho m)$ (which always concides with the closure $H^{1,p}(X,d,\rho m)$ of Lipschitz functions) with the ...

Quasi‐invariance of Gaussian measures for the 3d$3d$ energy critical nonlinear Schrödinger equation
Abstract We consider the 3d$3d$ energy critical nonlinear Schrödinger equation with data distributed according to the Gaussian measure with covariance operator (1−Δ)−s$(1-\Delta)^{-s}$, where Δ$\Delta$ is the Laplace operator and s$s$ is sufficiently large. We prove that the flow sends full measure sets to full measure sets. We also discuss some simple
