摘 要:
In this talk, we introduce some results on the existence and multiplicity of positive solutions for the following critical problem involving logarithmic term:
−Δu=μu2∗−2u+ν|u|q−2u+λu+θulogu2, x∈Ω, u=0, x∈∂Ω,
Where Ω⊂RN is a bounded smooth domain, ν,λ∈R,μ>0,θ<0,N≥3,2∗=2NN−2 is the critical Sobolev exponent for the embedding H01(Ω)↪L2∗(Ω) and q∈(2,2∗), and which can be seen as a Brezis−Nirenberg problem.
