Super Virasoro algebra

<p>In <a href="/facts/Mathematical_physics/sLKg8T1G">mathematical physics</a>, a super Virasoro algebra is an <a href="/facts/Lie_algebra_extension/CEBYBGvQ">extension</a> of the <a href="/facts/Virasoro_algebra/p84kseUl">Virasoro algebra</a> (named after <a href="/facts/Miguel_%25C3%2581ngel_Virasoro_(physicist)/zhmWnqLo">Miguel Ángel Virasoro</a>) to a <a href="/facts/Lie_superalgebra/c1oxUoEl">Lie superalgebra</a>. There are two extensions with particular importance in <a href="/facts/Superstring_theory/1gY26F0D">superstring theory</a>: the Ramond algebra (named after <a href="/facts/Pierre_Ramond/GIey1elq">Pierre Ramond</a>)  and the Neveu–Schwarz algebra (named after <a href="/facts/Andr%25C3%25A9_Neveu/Fb25m4Kc">André Neveu</a> and <a href="/facts/John_Henry_Schwarz/mmjLJe5S">John Henry Schwarz</a>). Both algebras have <a href="/facts/Supersymmetry_algebra/zUYT4vy6"><i>N</i> = 1 supersymmetry</a> and an even part given by the Virasoro algebra. They describe the symmetries of a superstring in two different sectors, called the Ramond sector and the Neveu–Schwarz sector.
