An inequality for vector functions 
, 
, and their derivatives, defined in some bounded domain 
of 
:
 | (1) |
where
 | (2) |
The Korn inequality is also valid for vector functions in the space 
obtained by completing the space 
with respect to the norm (2). The inequality (1) is sometimes called the second Korn inequality; the first Korn inequality being inequality (1) without the second term on the left.
The inequality was proposed by A. Korn (1908) in order to obtain an a priori estimate for the solution of non-homogeneous equations of elasticity theory.
