Young measure : ウィキペディア英語版 | Young measure In mathematical analysis, a Young measure is a parameterized measure that is associated with certain subsequences of a given bounded sequence of measurable functions. Young measures have applications in the calculus of variations and the study of nonlinear partial differential equations, as well as in various optimization (or optimal control problems). They are named after Laurence Chisholm Young who invented them, however, in terms of linear functionals already in 1937 still before the measure theory has been developed. ==Definition==
We let be a bounded sequence in , where denotes an open bounded subset of . Then there exists a subsequence and for almost every a Borel probability measure on such that for each we have in . The measures are called the Young measures generated by the sequence .
