Abstract
We show that large positive solutions exist for the following equationÎu+|âu|q=p(x)f(u)(p+)in Ω â RN (N ⥠3) in which the domain Ω is either bounded or equal to RN. The nonnegative function p is continuous and may vanish on large parts of Ω. If Ω = RN, then p must satisfy a decay conditionâ«0ârÏ(r)dr<â,whereÏ(r)=maxâ¡|x|=rp(x)as|x|ââ.Furthermore, we show that the given conditions on p are nearly optimal for equation (p+).
