Double phase equations with an indefinite concave term	2022	10	.pdf	application/pdf	4125	250	80	In (3.4) we choose h = un − u ∈ W 1,η 0 (Ω), pass to the limit as n → +∞ and use (3.16). Introduction Let Ω ⊆ RN be a bounded domain with a Lipschitz boundary ∂Ω. In this paper we study the double phase problem −∆a pu(z)−∆qu(z)	cache/ejde-145.pdf	txt/ejde-145.txt
