Regularity results for mixed local and nonlocal double phase functionals

Abstract: We investigate the De Giorgi-Nash-Moser theory for minimizers of mixed local and nonlocal functionals modeled afterwhere 0 < s < 1 < p ≤ q and a(•) ≥ 0. In particular, we prove Hölder regularity and Harnack's inequality under possibly sharp assumptions on s, p, q and a(•).

“…To some extent, our results in this work offset the scenario 𝑝 ⩽ 𝑠𝑞 that repels the center assumptions on growth exponents 𝑝, 𝑞 in [10,21]. Note that the hypothesis required in (1.5) and the center assumption on growth exponents 𝑝, 𝑞 in [11,22] are mutually exclusive. Finally, let us mention that given the condition 𝑝 ≠ 𝑞, the functional (1.1) is closely related to a large number of anisotropic local or nonlocal problems with nonstandard growth, see, for instance, [2,3,10,18,23,26,35].…”

“…Studies on regularity results for mixed local-nonlocal p-Laplacian type operators were initiated in the paper [36], where the De Giorgi-Nash-Moser theory was investigated by combining the techniques for the fractional p-Laplacian [28,29] with those for the classical p-Laplacian. We refer to [2,11,14,37,38,51] and references therein for further results concerning mixed local-nonlocal nonlinear problems. We would like to single out the paper [27] where maximal regularity, including (local) gradient Hölder regularity, was proved for a larger class of mixed problems related to −∆ p + (−∆ γ ) s with p, γ > 1 and s ∈ (0, 1) satisfying p > sγ.…”

Mixed nonlocal-local problems of the type II with the were considered by Byun, Lee, and Song [BLS23], where they obtained Hölder regularity results for such problems under the assumption s ∈ (0, 1) and 1 < p ≤ q.…”
