Abstract
This paper focuses on a nonhomogeneous quasilinear elliptic boundary blow up problem â³pu=a(x)f(u)+h(x)inΩ,u|âΩ=â,where p>1, Ω is a smooth bounded domain in Rn, and hâC(Ω) may be sign-changing in Ω and singular on âΩ. We mainly analyze the influences caused by h on the existence of large solutions. Furthermore, it can be verified that any large solution is nonnegative under an additional assumption.
