Concentration and multiplicity of solutions for fractional double phase problems
Abstract In the present paper, we consider the following fractional double phase problem with nonlocal reaction: \begin{align*} \qquad \quad \left\{ \begin{array}{lll} (- \Delta)_p^s u + (- \Delta)_q ^s u + V(\varepsilon x) (|u|^{p - 2} u + |u|^{q - 2} u) = \left(\frac{1}{|x|^\mu} * F(u)\right) f(u) & \ \text{in}\ \mathbb{R}^N, …
