要:Abstract. Functional inequalities establish embeddings of function spaces into others and it happens they are sometimes achieved and in others cases not achieved. However, it is the case that an integral inequality (x) holds in the Banach space X if and only if inequality (y) holds in the space Y and we say the two inequalities are equivalent. A remarkable fact is when one inequality is not achieved whence on the contrary the equivalent one is achieved. We show how this principle works in two significant cases, namely the Hardy and the Trudinger-Moser inequalities.
