Galilean Superconformal Symmetries
J. A. de Azcarraga, J. Lukierski
We consider the non-relativistic c -> \infty contraction limit of the (N=2k)- extended D=4 superconformal algebra su(2,2;N), introducing in this way the non-relativistic (N=2k)-ext…

Cohomology of Filippov algebras and an analogue of Whitehead's lemma
Jose A. de Azcarraga, J. M Izquierdo
We show that two cohomological properties of semisimple Lie algebras also hold for Filippov (n-Lie) algebras, namely, that semisimple n-Lie algebras do not admit non-trivial centra…
