Abstract (EN)
We show an extension result for functions in GSBD^p , for every p > 1 and any dimension n ≥ 2. The proof is based on a recent result in [9], where it is shown that a function u in GSBD^p with a "small" jump set coincides with a W^{1,p} function, up to a small set whose perimeter and volume are controlled by the size of the jump of u.Subjects / Keywords
