Motivation World-Sheet SUSY Lie superalgebras From World-Sheet SUSY to Supertargets Outlook<br />

Lie superalgebras and supergroups<br />

• Lie Superalgebra G = G 0 ⊕ G 1<br />

• Z 2 graded product<br />

[G 0 , G 0 ] ⊂ G 0 ( subalgebra)<br />

[G 0 , G 1 ] ⊂ G 1<br />

[G 1 , G 1 ] ⊂ G 0<br />

• Graded anti-symmetry<br />

[X, Y ] = −[Y , X]<br />

[X, Y ] = −[Y , X]<br />

[X, Y ] = [Y , X]<br />

• Generalised Jacobi identity
