In summary, the conversation revolves around trying to understand the relationship between various tensors and their components. The person is struggling with understanding the notation and definitions of various symbols, including Aijkl, Fijkl(am), A·B, and A-1. They also mention that F is a six-parameter family of tensors.

I can't make sense of any of that. Does Aijkl=Fijkl(am) mean that Aijkl is the result of letting Fijkl act on am? Then why doesn't A have five indices instead of four? Is am a vector or a component of a vector? Why doesn't m appear anywhere on the right? What are the definitions of A·B and A-1? (I haven't seen either defined for tensors with 4 indices). Does A denote the tensor and Aijkl its components in a coordinate system? Then what does A (no indices, not bold) denote?

Looks to me like F just takes a six-tuple of coefficients (what kind, who knows?) and spits out a rank-4 tensor. In other words, F is some six-parameter family of tensors. I suppose the answers will be in terms of the a_i's and b_i's (i=1,...,6).
