I'm prepared to say that this is too vague to be useful. Charles Matthews 04:18, 2 Aug 2004 (UTC)

What about something like:

A Killing spinor on a manifold M is a spinor field φ which satisfies
\nabla_X\phi=\lambda X.\phi
for all tangent vectors X, where \nabla is the spinorally covariant derivative and λ is a constant, called the Killing number. If λ = 0 then the spinor is called a parallel spinor.

What λX.φ means?

The dot in X.φ means Clifford multiplication. Just removed

The Killing Equation is analogous to Maxwell's equations, but abstracted to higher dimensions.

from the main page. I don't think the Killing equation has anything to do with Maxwell's equations. Dmr2 09:59, 27 Aug 2004 (UTC)
