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).
There are several modes of being able to view the proofs:
