Lagrange bracket
open-in-new
<p>Lagrange brackets are certain expressions closely related to <a href="/facts/Poisson_bracket/7WUH7VXV">Poisson brackets</a> that were introduced by <a href="/facts/Joseph_Louis_Lagrange/bTQUaSTv">Joseph Louis Lagrange</a> in 1808–1810 for the purposes of mathematical formulation of <a href="/facts/Classical_mechanics/ykG8upsN">classical mechanics</a>, but unlike the Poisson brackets, have fallen out of use. </p>
