On multidimensional Opial-type inequalities
The main aim of this note is to establish two new integral inequalities involving functions of n independent variables and their gradients which claim their origin to the inequality of Opial. An interesting feature of these inequalities is that the analysis used in the proofs is quite elementary and based on some simple observations and applications of fundamental inequalities.
