In mathematical analysis, Agmon's inequalities, named after Shmuel Agmon,[1] consist of two closely related interpolation inequalities between the Lebesgue space and the Sobolev spaces . It is useful in the study of partial differential equations.

Let where [vague]. Then Agmon's inequalities in 3D state that there exists a constant such that

and

In 2D, the first inequality still holds, but not the second: let where . Then Agmon's inequality in 2D states that there exists a constant such that

For the -dimensional case, choose and such that . Then, if and , the following inequality holds for any
