Consider the following eigenvalue problem of p-Laplacian equation where 0362546X1630236X&_mathId=si2.gif&_user=111111111&_pii=S0362546X1630236X&_rdoc=1&_issn=0362546X&md5=07e4e72d63b7a83231f7d78b8736cb0b" title="Click to view the MathML source">a≥0$a\ge 0$, 0362546X1630236X&_mathId=si3.gif&_user=111111111&_pii=S0362546X1630236X&_rdoc=1&_issn=0362546X&md5=fb59ca7b5681e621d619720d84aeb3a9" title="Click to view the MathML source">p∈(1,n)$p\in (1,n)$ and 0362546X1630236X&_mathId=si4.gif&_user=111111111&_pii=S0362546X1630236X&_rdoc=1&_issn=0362546X&md5=609a4706022c45810d0bbaf053221230" title="Click to view the MathML source">μ∈R$\mu \in \mathbb{R}$. 0362546X1630236X&_mathId=si5.gif&_user=111111111&_pii=S0362546X1630236X&_rdoc=1&_issn=0362546X&md5=23738ff89bab2cd8480e6cbef02a0e60" title="Click to view the MathML source">V(x)$V\left(x\right)$ is a trapping type potential, e.g., 0362546X1630236X&_mathId=si6.gif&_user=111111111&_pii=S0362546X1630236X&_rdoc=1&_issn=0362546X&md5=6bbe680d6ac873083aca90ad54851570" title="Click to view the MathML source">inf_x∈RⁿV(x)<lim_|x|→+∞V(x)${inf}_{x\in {\mathbb{R}}^n}V\left(x\right)<{lim}_{\left|x\right|\to +\infty }V\left(x\right)$.
