Abstract: We prove the absence of positive solutions for some semilinear elliptic partial differential inequalities with transformations of the argument in a half-space. The proofs are based on the test functions method.

Keywords: nonlinear elliptic inequalities, transformations of arguments, absence of solutions, positive solutions, monotonic solutions.
