Γ-convergence, Sobolev norms, and BV functions
We prove that the family of functionals (Iδ) defined by Iδ(g) = ∫∫ RN×RN |g(x)−g(y)|>δ δ |x− y|N+p dx dy, ∀ g ∈ L(R ), for p ≥ 1 and δ > 0, Γ-converges in L(R ), as δ goes to 0, when p ≥ 1. Hereafter | | denotes the Euclidean norm of R . We also introduce a characterization for BV functions which has some advantages in comparison with the classic one based on the notion of essential variation o...
متن کاملNon-degeneracy of Sobolev Pseudo-norms of fractional Brownian motion
Applying an upper bound estimate for small L2 ball probability for fractional Brownian motion (fBm), we prove the non-degeneracy of Sobolev pseudo-norms of fBm.
متن کاملRelations between Sobolev and Kantorovich norms on manifolds with curvature conditions
We prove several multiplicative inequalities relating the Kantorovich norm with the Sobolev norm for functions on a Riemannian manifold satisfying certain curvature conditions.
متن کاملCharacterization of Sobolev and BV Spaces
The main results of this paper are new characterizations of W (Ω), 1 < p < ∞, and BV (Ω) for Ω ⊂ R an arbitrary open set. Using these results, we answer some open questions of Brezis [11] and Ponce [32].
متن کاملGrowth of Sobolev norms of solutions of linear Schrödinger equations on some compact manifolds
We give a new proof of a theorem of Bourgain [4], asserting that solutions of linear Schrödinger equations on the torus, with smooth time dependent potential, have Sobolev norms growing at most like t when t→ +∞, for any > 0. Our proof extends to Schrödinger equations on other examples of compact riemannian manifolds.
