Lorentz Invariance Breakdown: A Brief Survey Embedding Problem or Cancellation Problem for complex affine spaces would reverberate across the whole of algebra, and we have seen how locally nilpotent derivations might play a role in their solution. Following are several additional directions for future inquiry.

Further Properties of LNDs,assumption that . is a commutative .-domain, where . is a field of characteristic zero. Subsequent sections discuss quasi-extensions, .-critical elements, the degree of a derivation, trees and cables, exponential automorphisms, construction of kernel elements by transvectants and Wronskians, and rec
