On a new class of fractional partial differential equations
Tien Tsan Shieh,Daniel Spector +1 more
TL;DR: In this paper, a new class of fractional partial differential equations which are obtained by minimizing variational problems in fractional Sobolev spaces is introduced, which has the potential to extend many classical results in the Soboleve spaces to the nonlocal and fractional setting in a natural way.

Characterization of Sobolev and BV Spaces
Giovanni Leoni,Daniel Spector +1 more
TL;DR: In this article, new characterizations of W 1, p (Ω ), 1 p ∞, and BV ( Ω ) for Ω ⊂ R N an arbitrary open set were given.

On formulae decoupling the total variation of BV functions
Augusto C. Ponce,Daniel Spector +1 more
TL;DR: In this paper, it was shown that rescalings of the fractional Laplacian of a function u ∈ S B V converge strictly to the singular portion of D u.
A Boxing Inequality for the Fractional Perimeter
Augusto C. Ponce,Daniel Spector +1 more
TL;DR: In this article, the Boxing inequality was shown to imply a trace inequality in the fractional Sobolev space, where the Hausdorff content of the space is the Euclidean distance from the dimension of the input dimension.

Optimal embeddings into Lorentz spaces for some vector differential operators via Gagliardo’s lemma
TL;DR: In this paper, a family of Sobolev inequalities on Lorentz spaces was shown to imply the extension of the classical Gagliardo-Nirenberg inequality to the case of first order homogeneous linear differential operators.
