摘要 The authors consider the following equations: $$\\Delta u=k(x)h(u)+H(x)\\int_{\\bold R^n}a(y)q(u(y))\\,dy\\tag1$$

in $\\bold R^n$ $(n\\geq 2, \\Delta$ a Laplacian operator), with $h,q$ convex, $K$, $H$ locally Hölder continuous and nonnegative; $$\
abla \\cdot[g(|\
abla u|)\
abla u]=K(|x|)h(u)+H(|x|)\\int_{\\bold R^n}a(|y|)q(u(y))\\,dy,\\tag2$$

where $g$ takes values in some bounded interval $[0,x]$ and its main property is $(pg(p))`>0$.
Their goal is to prove that in both cases no positive and bounded solution exists under additional assumptions. For instance, adding some requirement on the functions $q,h$, it is shown that there is no positive solution of $(1)$ such that its average over $|x|=r$ has a prescribed limit for $r\\to 0$.
The authors prove several theorems of this type. These results are obtained through a series of lower estimates on the average of $u$ which eventually are shown to be inconsistent with the existence of any positive solution.
