Regularity for Mixed Local and Nonlocal Degenerate Elliptic Equations in the Heisenberg Group
Junli Zhang, Pengcheng Niu
In this paper, we investigate the regularity for mixed local and nonlocal degenerate elliptic equations in the Heisenberg group. Inspired by the De Giorgi-Nash-Moser theory, the lo…
