Can anyone tell me if it is possible to perform the following tensor-
manipulations with Maple:
- automatic Einstein summation convention,
- convenient notation for partial derivatives (like g[a,b,c] for
\partial_c g_{a,b} )
- automatic relabeling of indices whenever a substitution is made
(eg. A=B(mu)*B(mu); C=A*A; MAPLE: C=B(mu)*B(mu)*B(N1)*B(N1) )
