Shear-Free Proofs in General Relativity download page

This page contains the links to download the MAPLE-based original proofs of the shear-free conjecture, as presented in covariant formalism.

 The original equations are published in;

 Senovilla, J.M.M., Sopuerta, C.F., Szekeres, P. Theorems on shear-free perfect fluids with their Newtonian analogues, Gen.Rel.Grav, 30, 389-411 (1998).

The independent proofs attached here are the original work of Peter Huf and John Carminati.( see Huf, P.A.a* & Carminati, J.a (2014). Elucidation of covariant proofs in general relativity: example of the use of algebraic software in the shear-free conjecture in MAPLE (in preparation).
