Web1 de abr. de 2024 · In particular, two new families of one-sided fractional Sobolev spaces are introduced and analyzed, they reveal more insights about another family of so-called symmetric fractional Sobolev spaces. In the integer order case, an alternative way to define Sobolev spaces is to use the completion spaces of smooth functions under chosen Sobolev norms. The goal of this subsection is to establish an analogous result for fractional Sobolev spaces introduced in Sect. 3.1. To this end, we first need to introduce spaces that we … Ver mais Let $\alpha >0$ and $1 \le p \le \infty$. We define 1.
