Wess–Zumino–Witten model

<p>In <a href="/facts/Theoretical_physics/Cs2Y12rQ">theoretical physics</a> and <a href="/facts/Mathematics/pxTouaz4">mathematics</a>, a Wess–Zumino–Witten (WZW) model, also called a Wess–Zumino–Novikov–Witten model, is a type of <a href="/facts/Two-dimensional_conformal_field_theory/xHpQ5dbW">two-dimensional conformal field theory</a> named after <a href="/facts/Julius_Wess/FCuYE0cI">Julius Wess</a>, <a href="/facts/Bruno_Zumino/t1SoURWu">Bruno Zumino</a>, <a href="/facts/Sergei_Novikov_(mathematician)/hqMGDRul">Sergei Novikov</a> and <a href="/facts/Edward_Witten/lPUylPmj">Edward Witten</a>. A WZW model is associated to a <a href="/facts/Lie_group/a9jCQyjF">Lie group</a> (or <a href="/facts/Supergroup_(physics)/m7U6FFVR">supergroup</a>), and its symmetry algebra is the <a href="/facts/Affine_Lie_algebra/uCBnNs1l">affine Lie algebra</a> built from the corresponding <a href="/facts/Lie_algebra/n2gAUkNq">Lie algebra</a> (or <a href="/facts/Lie_superalgebra/c1oxUoEl">Lie superalgebra</a>). By extension, the name WZW model is sometimes used for any conformal field theory whose symmetry algebra is an affine Lie algebra.
