We prove the existence of the least positive eigenvalue with a corresponding nonnegative eigenfunction of the quasilinear eigenvalue problem - div ( a ( x , u ) | | p - 2 ∇ u ) = λ b ( x , u ) | u | p - 2 u in Ω , u = 0 on ∂ Ω , where Ω is a bounded domain, p > 1 is a real number and a ( x , u ) , b ( x , u ) satisfy appropriate growth conditions. Moreover, the coefficient a ( x , u ) contains a degeneration or a singularity. We work in a suitable weighted Sobolev space and prove the boundedness of the eigenfunction in L ∞ ( Ω ) . The main tool is the investigation of the associated homogeneous eigenvalue problem...
